1. CHAPTER 2: LESSON 2:
HOW DO PLANTS
GROW, DEVELOP
AND
REPRODUCE?

2. Parts of the plant
Flower
Stem
Leaves
Roots

3. Needs of plants
Water
Sunlight
Nutrients
Carbon dioxide

4. Functions of Parts of the plant
The flower forms seeds and
fruits.
(production of new plants)
The stem takes water and
nutrients from the roots.
The Leaf takes water and nutrients
(from stem) and sunlight and carbon
dioxide (from the air) to make the
plants food.
1) Anchors the plant in the soil.
2)The roots takes water and
nutrients from the soil.

5. PARTS OF A FLOWER

7. Sepal
Protects the bud.

8. Stigma
Stame
n
The male
part of the
flower. (The
anther
produces
pollen)
Anthe
r
Filame

(Sticky surface
to catch the
pollen)
Style
(Tube)
Ovary
Pistil
(The
female part
of the
flower)
(Tube)
Petal
Brightly
coloured to
attract insects.

9. Pollinatio
n
(The transfer of
pollen from stamen
to pistil)

10. Ways of Pollination
By
insects or
birds
By wind

11. Pollination by insects or
birds
Nectar (sweet liquid), colourful petals and scent
attract the insect and birds
Pollen sticks to their body.
When pollinator goes to another flower the
pollen sticks to the pistil.

12. Types of
Pollination
Self
pollination
Cross
pollination
The male pollinates
the female of the
same flower.
The male pollinates
the female of
another flower.

13. What happens after Pollination?
A pollen tube grows from the pollen to the egg.
The pollen enters the egg (FERTILISATION)

14. What happens after fertilisation?
A pollen tube grows from the pollen to the egg.
The pollen enters the egg (FERTILISATION)

15. Structure of seed
Protects
the seed
Stores
food for
embryo.
Baby plant
