Life cycle of plants

1. LIFE CYCLE OF PLANTS
Unit 3 – Science Fusion

2. What is a life cycle?
• The stages an
organism or living
thing goes through
during its life. The
stages form a cycle
that repeats again
and again.

3. How does the life cycle of a plant
begin?
• Most plants come from seeds. A seed
germinates when it breaks open and a small
plant grows out of it.

4. FLOWERS
• A flower is the part of some
plants when they become
adults. The flower enables
them to reproduce (make
more plants similar to
themselves)
• Flowers have male and
femal parts that are
involved in reproduction.

5. Seed: it has a hard
outer covering to
protect it.
Seedling: it is the
tiny new plant that
comes out of the
seed.
Adult Plant: the
seedling grows into
an adult plant.
Fruit: flowers fall off the
plant and the plant
makes a fruit. The fruit
holds the seeds.

6. CONES
• Some plants make seeds without flowers.
Their seeds form in cones.
• Cones are the parts of some seed plants
where reproduction occurs. Cones do not
develop into fruit.

7. POLLEN
• It is a powder-like material involved in plant
reproduction. Plants that make seeds also
make pollen.

8. POLLINATION
• It happens when pollen is moved from the
male plant part to the female plant part.
• The environment around a plant helps in
pollination.
• Wind, water, and animals help move the
pollen from plant to plant.

9. The pistil is the
female part. The
seeds form in
here!
The stamen is the
male part.

10. Seeds are carried to new areas thanks
to water, wind, and animals. Look at
some examples:
• Birds eat fruit, the seeds will
pass through its body. The seeds
may be left in a new place.
• Seeds may float in the wind and
moved to new ground.

11. SPORES
• Spores are reproductive structures that can
grow into new plants.
• Ferns are one type of plant that reproduces
using spores. They have leaves called FRONDS.
Each frond has smaller leaves.

12. SPORES
• Moss is another type of plant that reproduces
using only spores. Mosses are small, soft
plants. They usually grow in damp (wet)
places.
