Plants have different reproductive organs like stamens and carpels. The stamens produce pollen as the male organ and the carpel contains the female organs like the stigma and ovary. Pollination is the transfer of pollen from the stamen to the stigma, which can occur through animals or wind. When pollen reaches an ovule in the ovary, fertilization happens and a seed is formed. Plants provide food, medicine, clothes and oxygen through their life processes like photosynthesis.

2. PLANTS AROUND US
Plants around us can be different
shapes, sizes and colours.

3. Plants give us food,
medicine,
clothes
and oxygen.

4. Plants have different life processes:
nutrition
interaction
reproduction

5. We can classify plants into:
herbaceous plants, bushes and trees.

6. THE REPRODUCTIVE ORGANS
OF A PLANT
The flower is the reproductive organ of
a plant.
Most flowers have male and female
reproductive organs.

7. THE STAMENS
The stamens are the male reproductive
organs and these produce pollen.

8. THE CARPEL
The carpel is the female reproductive
organ.

9. THE CARPEL
The carpel includes the stigma and the
ovary. stigma

produces
ovules.

18. POLLINATION
Pollination is the transfer of pollen from
the stamens to the stigma of a flower.

19. TYPES OF POLLINATION
Pollination can be:
Animal pollination

20. TYPES OF POLLINATION
Pollination can be:
Animal pollination Wind pollination

21. ANIMAL POLLINATION
Animal pollination is carried out by
birds, insects and other animals.

22. Colourful petals attract animals to a
flower. These animals come to the plant
to drink a sweet liquid called nectar.

23. Pollen from the stamens sticks to the
animal’s body.

24. Pollen from the stamens sticks to the
animal’s body.
When the animal travels to another plant,
some of the pollen on its body is
transferred to the other plant.

25. WIND POLLINATION
Wind pollination is used by plants
such as trees and grasses which
don’t have colourful petals to attract
animals.
The wind blows pollen from the
stamens of these plants to the stigma.

26. FERTILIZATION
Fertilization is when pollen joins
with an ovule.

27. The fertilization process happens in
the stigma.

28. The fertilization process happens in
the stigma.
The fertilized ovule becomes a seed.

29. The fertilization process happens in
the stigma.
The fertilized ovule becomes a seed.
The stigma develops and forms a
fruit around the seed.

30. When a seed lands in soil it can
germinate and a new plant grows.

31. HOW PLANTS MAKE THEIR
OWN FOOD
Plants need water, minerals, carbon
dioxide and light and energy from the
Sun to make their own food.
Minerals

32. Plants make food in their leaves.
This process is called photosynthesis.

33. The leaves absorb carbon dioxide
from the air through small holes.
Using energy from the Sun, the carbon
dioxide combines with water, minerals
and sunlight to make food.
minerals

34. During the process of photosynthesis,
plants release oxygen into the air.
People and animals need oxygen to
breathe.
