8. Sunlight—Plants get energy from the Sun. Chlorophyll found in
plant leaves uses sunlight to change water, minerals, and
carbon dioxide into food. This process is called photosynthesis.
Water—Plants must have water because it helps carry nutrients from the
soil to the plant's roots. Water is a part of plant cells and is a main ingredient for
photosynthesis.
Minerals—Plants need soil because they use it to get water, nutrients, and minerals.
Air—Plants also get nutrients from the air. During photosynthesis, plants take in carbon
dioxide from the air and release oxygen.
Space—Plants also need space to grow. If there are too many plants for the amount of
sunlight, soil, minerals, or space, some of the plants will not survive
9. Roots—Roots anchor the plant in the soil, take in
water from the soil, and take in nutrients from the
soil.
Leaves—Leaves are where photosynthesis mainly
takes place. Leaves take in carbon dioxide from the air
and absorb sunlight energy. Both of these things are
needed in order for the plant to make food through
photosynthesis. Leaves exchange gases with the
atmosphere through holes called stoma.
Stems—Stems provide structure for the plant and
allow water and nutrients to travel throughout the
plant. The stems of some plants can also help the
plant to reproduce. If the stem is planted in the
ground correctly, a new plant will grow

and absorb sunlight energy. Both of these things
are needed in order for the plant to make food
through photosynthesis. Leaves exchange gases
with the atmosphere through holes called stoma.
12. • Plant part that is
responsible for food
production through
Photosynthesis.
• The Leaves/Needles
are also where gas
exchange takes
place. Carbon
Dioxide goes in, and
Oxygen comes out.
Leaves
14. • Plant part that is
responsible for
supporting the upper
plant parts.
• The Stem also transports
water/nutrients from the
roots to the leaves and
transports food (sugar)
back from the leaves down
to the roots.
Stem
15. Flowers allow the plant to reproduce.
They produce pollen and also the eggs
that the pollen will fertilize. Once a
flower is pollinated, the flowers can
produce seeds and fruit.The petals are
the parts of the flower that attract
pollinators, such as insects. Petals are
usually brightly colored.
16. • Plant part that is
responsible for
plants reproducing
new seeds through
plant reproduction.
17. • Plant part that
is formed
around the

from the ground.
• Roots are also the
anchor that holds
the plant in the
ground.
Roots
20. Seeds of a plant can grow into new plants
once they get into the soil.This allows the
plant to reproduce. Some seeds have
special structures to help them get to a
new piece of ground. Dandelion seeds
have light hairs that catch the wind to
blow them away. Burrs have sharp spines
that get caught in animals' fur, carrying
the seeds away.
21. • Plant part that is
responsible for
making a new
plant (Embryo).
• Seeds have
enough food in
them to start an
Embryo and are
usually found in
the plant’s fruit.

47. The Parts of a Flower
• Sepals protect the bud until
it opens.
• Petals attract insects.
• Stamens make pollen.
• Pistil contain the ovary
which contains the ovules
(eggs).
• When fertilized, ovules
grow into fruits which
contain seeds.
50. Parts of a flower
• The male part of the flower is the stamen which
include the anther and filament.
– The anther produces pollen grains.
• The female parts of the flower is the pistil which
includes the stigma, style, ovary and ovule.
58. Pollination
• Pollination is the transfer of pollen grains
from the anther to the stigma of a flower.
– The pollen grains can be transferred within the
same flower.
stigma pollen grains
from anther
Pollination=
moving
from the
stamen to
the pistil
59. Pollination
• Pollen grains can be transferred by wind, insects,
bats and birds.
– The pollen grains can also be transferred from one
flower to another.
60. What is Pollination?
Gizmos: Flower Pollination
Pollination is the act of transferring pollen grains from
the male anther of the stamen to the female stigma.
Pollen lands on a female pistil, sperm cells move
down to the ovary, fertilizing the egg cells.
Fertilization combines DNA.
The result is a seed with a tiny plant inside.
The ovary grows into a fruit to protect the seeds.
63. Pollinators
Animals, wind, and water can all
help in the transfer of pollen.
We call animals or insects that
transfer pollen from plant to plant
"pollinators ".
The flower type, shape, color, odor,
nectar, and structure vary by the
type of pollinator that visits them.
64. Wind Pollination
Some flowers, such as grasses, do not
have brightly colored petals and nectar
to attract insects. These flowers are
pollinated by the wind.
65. Flowering plants use:
• the wind
• insects
• bats
• birds
• mammals
to transfer pollen from the stamen (male)
part of the flower to the stigma (female)
part of the flower.
66. Check Point
• What is pollination?
• How do flowering plants depend on other
living things in order to reproduce?
• Why are young plants like but not identical to
their parents?
67. Fertilization
• After pollination a flower
becomes fertilized.
• Fertilization is when the
female egg cell and the male
sperm cell combine.
• A tube containing the male
sperm cell grows down the
style to reach the ovules in
the ovary.
• Inside each ovule is an egg
cell.

70. From flower to fruit
After fertilization, most
of the flower parts
wither and drop off
except for the ovary.
Inside the ovary, the
ovules begin to
develop into seeds.
The ovary then grows
bigger until it becomes
a fruit.
seeds develop inside the
fruit, fruit grows bigger
petals drop off
ovary begins
to swell
petals wither
flower (after fertilization)
72. Seed Dispersal
• Seeds can be easily carried by
wind, water, or animals.
• Some fruits can be eaten by
animals and the seeds are
then dispersed.
73. How do seeds get dispersed
from a plant into the ground?
• Some seeds are hidden in the ground by animals such as
squirrels as a winter store.
• Some seeds have hooks on them and cling to fur or clothes.
74. How do birds and animals
help seed dispersal?
Birds and animals eat the
fruits and excrete the seeds
away from the parent plant.
75. Ways Seeds are Carried Away from a Plant
• Animal-carried
• Animal-consumed
• Water-borne
• Wind-borne
• Propelled
80. Seed Germination
• Water
• Oxygen
• Proper temperature
• Some require proper light
What do seeds need to sprout?

What is the function of each part of
the nonflowering cone-bearing
plant?
•Leaf/Needle?
•Cone?
•Stem/Trunk?

87. Non - flowering Plants
• Some plants don’t produce flowers and
seeds.
• Non-flowering plants such as ferns and
mosses produce spores instead of seeds.
89. Some plants reproduce with
seeds, while other plants
reproduce with spores.
Let’s look at the difference
between seeds and spores.
90. What are seeds?
• A seed is the start
of a new plant
• Seeds can be
different shapes,
sizes, and colors
• Seeds are
produced in
flowers
Lima bean plant
with flowers
Green lima

white seeds
91. What are the parts of a seed?
• Seeds are protected
by a seed coat
• Seeds contain tiny
leaves and a root
• Seeds contain
stored food for the
new plant
92. Gone to Seed
Three main parts:
1. seed coat - a covering with two roles:
- Protects new plant called embyro
- Guards stored food called endosperm.
2. endosperm – stored food
3. embryo – The new plant with structures called
seed leaves or cotyledons.
93. What are the parts of a seed?
A B C
Which part of the seed does each letter represent?
Which part of the seed is not shown in the
photograph?
95. Observing a Seed
1. Observe the outside of a dry bean seed with a hand
lens. Draw it and write down four or more properties
including length and width.
2. Get a wet bean seed to observe. Draw it and write
down four or more properties including length and
width.
3. Why is the wet seed larger?
4. Split it open and observe its parts. Draw and label its
inside including the seed coat, cotyledon, and
embryo.
97. Seeds are scattered by planting, wind, water,
and animals.
When the small plant inside begins to grow, the seed
germinates.
The young plant that grows from a seed is the
seedling.
Remember…
98. What are some plants that produce seeds?
corn
pine tree sunflower
99. DO ALL PLANTS MAKE SEEDS TO
REPRODUCE?
Ferns and Mosses do not grow
seeds. Instead they produce
spores.
104. What are some plants that
produce spores?
ferns
mosses
105. Ferns DO NOT have seeds. Instead, they reproduce
with spores. A spore is a tiny part of a fern that can
grow into a new plant. Spores DO NOT have a food
supply for the young plant like seeds do.
106. Characteristics of Ferns
• Ferns are plants that reproduce through spores
which are found on the underside of leaves.
• Ferns can be found in damp and shady places.
• They have roots, feathery leaves, and
underground stems.
108. This fern has big leaves divided into many smaller
parts. It has “dots” on them. The “dots” on the
underside of the leaves are cases where spores
grow. Spore cases have spores inside them.
109. Characteristics of Mosses
• Mosses are some of the simplest
plants with simple stems and leaves.
• Mosses have spores which can be
found inside a capsule.
• The spores are dispersed by the wind.
118. Characteristics of Cone-bearing
Plants
• They reproduce with cones.
• They are tall evergreen trees with
roots and a woody stem.
• They have needle-shaped leaves.
• They are usually found in dry places.
120. WHAT ARE CONIFERS?
Conifers are non-flowering
plants that grow seeds just as
most plants do. Their seeds are
found in CONES which makes
them unique…

pine cones, which are spread throughout
the forest by the wind and/or animals.
124. 2. What is the main difference between the way a fern
and an orange tree reproduce?
Answer: An orange tree is a type of flowering plant that
reproduces by means of seeds.
A fern is a nonflowering plant that reproduces by means
of spores.

Orange
Trees
126. Plants
Respond to
Stimuli
SC.3.L.14.2 Investigate and
describe how plants respond to
stimuli (heat, water, gravity),
such as the way plants stems
grow toward light and their
roots grow downward in
response to gravity.
127. ESSENTIAL QUESTION
• How Do Plants Respond To Different Changes
In Their Environment?
• Think about what plant part is responding and
how that change is allowing the plant to adapt
and survive.
128. What is Stimuli?
• Stimuli is when a plant responds to its environment.
(Adaptations to its surroundings.)
• When plants change how they grow or move it is
called Tropism – growth or movement
• Examples are
• Plants roots grow towards water (hydrotropism)
• Stems grows towards light (phototropism)
• A plant grows vertically and roots grow down to the
pull of gravity (gravitropism or also referred to as
geotropism.
• Plant responding to heat thermotropism
129. Response to Stimuli
As they grow, plants respond to conditions around them.
Light
Gravity
Water

different stimuli?
Office of Academics - Department of Science
131. What are the plants doing in each of
these pictures??
132. Light
• Some plant parts grow, or turn towards the sun.
Plant parts include leaves, stems, flowers
• A plant can take in more light if it faced the sun.
• Leaves must take in light to make food for the
plant.
• Turning towards the sun helps a plant make the
food it needs.
Why do leave and stems of plants often grow
upward?
136. What are the plants
doing in these
pictures? What is it
called?
It’s gravitropism or geotropism!
137. Gravity
• Gravity causes roots to grow
downward.
– Growing downward helps roots reach
water and nutrients in soil.
– It helps roots to support the plant. (Roots
help keep water and wind from carrying
the plant way).
• Stems grow upward away from the pull
of gravity.
– It helps the leaves face the sun and take in
light.
139. Plants Respond to Gravity Too
On its side or upside down. Plants use the
force of gravity to get right side up.
Office of Academics - Department of Science
145. Heat- Temperature
• In places with cold winters, many flowers
bloom in spring.
• Some flowers can bloom any time it gets
warm enough.
• Some fruits will not get ripe in cool
weather.
• Many plants stop growing new leaves or
flowers when it gets cold.
– Helps them to live without water or enough
sunlight.
146. Some flowers open during the day and
close at night.
• Dandelion
• Water Lily
• Lotus Flower
147. Plants need Heat Energy
In order for seeds to sprout (germinate) they need heat
energy and water. Too much or too little heat will not allow
the seed to germinate. Once they have sprouted, they need
LIGHT and water more so than HEAT so that photosynthesis
can then occur in the leaves.
Plants react to
cold by folding
up to save
Heat Energy.
Different plants
grow at different
temperatures.
Some plants will
only grow under
the right
temperature
conditions.
148. Heat
• Plants do have natural systems that respond to
heat problems. Transpiration is a mechanism in
plants to cool themselves by “pumping” water
out through the leaves for a kind of swamp-
cooler effect.
• If temperatures increase chemicals (proteins)
inside the plant surround other “proteins” so
the plant can keep its shape.

cycles of Florida plants and animals, such as those
that undergo incomplete and complete
metamorphosis, and flowering and non-flowering
seed-bearing plants.
Essential Question:
What similarities and differences exist in the
life cycles of Florida plants and animals?
162. Life Cycles
All living things grow and change in
predictable patterns called life cycles. A
life cycle is defined as the complete
succession of changes undergone by an
organism during its life. A new cycle occurs
when an identical set of changes is begun.
165. Life Cycle of Plants
Most plants go through a similar life cycle.
Follow the life cycle of a lima bean plant.

169. Plants
• Plants come from seeds. Each seed contains a tiny plant waiting for the
right conditions to germinate, or start to grow. Seeds wait to germinate
until three needs are met: water, correct temperature (warmth), and a
good location (such as in soil). During its early stages of growth, the
seedling relies upon the food supplies stored with it in the seed until it is
large enough for its own leaves to begin making food through
photosynthesis. The seedling's roots push down into the soil to anchor the
new plant and to absorb water and minerals from the soil. And its stem
with new leaves pushes up toward the light. The germination stage ends
when a shoot emerges from the soil. But the plant is not done growing.
It's just started. Plants need water, warmth, nutrients from the soil, and
light to continue to grow.
170. Comparing Plant Life Cycles
Some plants produce flowers
Other plants produce cones or
spores
Department of Science
174. seed
Seed—Seeds are reproductive structures that some
plants produce. Each seed contains a tiny baby
plant and the food the plant will need to break out
of the seed, grow up through the soil, and grow its
first leaves.
187. What is photosynthesis?
• Process plants use to make their own food
• Plants’ leaves contain chlorophyll
• Chlorophyll (green color) makes
photosynthesis possible
189. What is needed for
photosynthesis to occur?
• Light is needed for photosynthesis to occur.
The plant’s leaves use the light to make a
sugar called glucose.
190. Plants make their own food
in their leaves using four
ingredients:
1. Sunlight from the sun
2. Water
3. Carbon dioxide (CO2)
4. Chlorophyll from the
leaves
How does Photosynthesis work?
191. The chlorophyll in
the leaves captures
the sunlight’s
energy and along
with the water and
carbon dioxide
plants produce a
food called sugar
and release oxygen.
How does Photosynthesis work?
192. Photosynthesis
• Photosynthesis is the process of making
food by plants
• The essential ingredients in making this
food are sunlight, the chlorophyll that is
present in green plants, water and carbon
dioxide in the air.
193. How it All Works Together?
In Photosynthesis,
a plant produces
plant sugar and
Oxygen using light
energy. The
leaves use water
and nutrients
transported by the
Roots and through
the Stem, and the
Carbon Dioxide
from the Leaves
and changes them
using Light as
energy.
194.
195.
196. Water is taken in through the roots of the
plant and transported to the leaves by
the xylem (tubes that carry water) in the
stems.
197. The Carbon dioxide
animals breathe out
goes into the leaves
through the tiny pores
called stomata. It then
spreads to the cells
that contain
chlorophyll in the
inside layer of the leaf.
202. Sunlight is used to break down the water in the
plant into oxygen which the plant gives off and
we use to breathe.
203. The hydrogen is then used with the carbon
dioxide to create the food for the plants and
ultimately food for animals as well.
204.
205. Why do plants need glucose?
• Glucose is the food for the plant. It gives
the plant energy to grow.
206. How much glucose does a plant
make?
• Plants make enough glucose to be used during
the night and on cloudy days when they don’t
get sunlight. The extra glucose is stored in the
plant’s leaves and other parts.
207. Photosynthesis is necessary not just for plants to
make food for themselves, but for animals,
including us eventually.
210. Animals including humans make the CO2
(carbon dioxide) plants need.
They (the plants) make the O2 (oxygen)
and food we need.
211. How does photosynthesis help us?
• During the process of photosynthesis,
oxygen is produced. We use this oxygen to
breathe.
212.
213. How does photosynthesis work?
Draw an illustration with captions to explain how plants
make their own food through Photosynthesis.
Vocabulary to include:
carbon dioxide (CO₂) chlorophyll leaves
