This document discusses the importance of plants and their basic biology. It explains that plants are essential to human life by providing food, medicine, clothing and oxygen. Plants perform photosynthesis to produce their own food from sunlight, water and carbon dioxide. The key parts of plants - roots, stems, leaves, flowers and seeds - are described along with their functions. Plants need soil, water, sunlight and air to grow. The document also provides some fun facts about different plants.

1. PLANTS

2. Why do you think plants are important
in our daily life ??
◦ Plants are important in our daily lives because –
Food-Plants are the main sources of food for humans . They make their own food by water,
sunlight, and air . This process is called photosynthesis.
Medicine-Plants are a very good and natural source for medicines and for diseases.
Like Aloe Vera- It heals the dull skin and heals the skin problems.
Clothing-Plants are the largest producers fabric materials.
These materials are not harmful to the environment, suitable and cheap.
So they are used for making clothes which humans require the cotton (cotton t-shirt)

3. Photosynthesis
◦ Photosynthesis is something that a pant does to live, like we humans need
energy to live even plants do.
◦ Photosynthesis is the process of making energy.
◦ The food or the energy for the plant is sugar or glucose .
◦ So when they absorb the sun, water, minerals and the Co²(carbon-dioxide)
they make their food.

4. What do plants need to grow and why??

5. Soil
Plants need soil to grow
because they contain
nutrients.
Fact
Not all of the plants require soil but some do.!

6. Water
Plants need water
to strengthen the
stem and leaves.Like
us we need energy,
even they conserve
energy.Plants also
need water for
photosynthesis which helps them making food
and giving out energy to the parts of the plant.

7. Sunlight
Plants need sunlight to
perform photosynthesis.

8. Air
Plants need air to breathe and to
make photosynthesis which gives
them energy and some food like
us…..

9. PARTS OF A PLANT.

10. There are 5 major parts of a plant:
ROOTS
STEM
LEAVES
FLOWERS
SEED
*The parts of a plant are hyperlinked..
But you can keep going to the next slide too

11. Roots
Roots absorb the water from the soil.
Roots absorb the nutrients from the soil.
Roots absorb the minerals from the soil also.
Roots holds the plants in the place
To prevent soil erosion.
Roots also store the food.

12. STEM
Stem supports the leaves, flowers and the other parts of the plant.
Transports water and minerals form the roots to the stem.
Also for food storage.

13. Leaves
The process of producing food , photosynthesis
which is processed by the leaves.
Like all living beings need air, also the plants need
air to breathe, the leaves have the stomata which
helps it to breathe.
The leaves also take in sunlight.

14. FLOWERS
The flowers have the male part called staemen,
and the female part called pestil.
They both produce seeds.
They also fertilize the plants.
The petals of the flowers attracts some insects to
pollinate them.

15. SEEDS
Dispersal to a new plant in another location by
the process called seed dispersal.
Dormancy during the unfavorable conditions.

16. Dormancy
◦Dormancy is when the physical activities, growth and
development has stopped . It is the state of inactivity
of plants . It happens when the plants are waiting for
their favorable conditions or nutrients e.t.c.

17. Fun Facts !!!!!
A pineapple is a berry.
If you inhale a pea , it will start growing in your lungs.
The oak trees don’t produce acorns until they are around 50 years old.
Black bat flower has underground bulb which is used for storing of nutrients.
A lupine also produces a two - color flower.
Flowers of iris were symbol of faith, wisdom and courage in the ancient Egypt
A starfruit is a everlasting plant that can survive around 45 years in the wild.
