1. HOW DO SEED
PLANTS GROW
REPRODUCE?
&

2. WHAT
CAN YOU SEE IN THIS PICTURE?
These are seeds

3. Plants are just like us, they have babies &
make new plants
-So, A seed is a baby plant

4. SEEDS
They are plants that are not fully formed 

5. PARTS OF A SEED
- A seed has 3 parts: 
1) Seed coat : A cover that protects the seed. 
2) Embryo: The baby plant. 
3) Stored food. 
Seed coat
Stored food
Embryo

6. WE CAN CLASSIFY THE SEEDS ACCORDING TO
Seed structure
- Water melons have flat small
seeds.
- Mangos and peaches have one
seed.
- Coconuts are giant seeds.
Where are seeds stored
- Flowers that bear “make”
seeds like: Apple trees
- Seeds found on the surface
of the cones like: Pine trees..

7. A PINE TREE
A pine tree contains two types of cones:
1) A Male cone.
2) A Female cone.

8. REPRODUCTION IN PINE TREES
Male cone
Female cone
-Small cones.
-Bigger cones.
-Present below the female
cones on a conifer tree.
-Present above the
male cone in a conifer
tree.
-Produce pollens “Yellow
powder”
-Produce “make” the
seeds when the
pollens are carried by
the wind and land on
the female cone

9. THE FLOWER
- The flower is the part of the plant which
is responsible for reproduction .
-Most of the flowers have 2 parts:
1) Male part
Anther
(Stamen)
Filament
2) Female part
(Pistil)
Stigma
Style
Ovary
Ovule

10. THE FLOWER STRUCTURE
Pollen tube

Stigma

Sepal

11. POLLINATION

- Now let’s see what happens inside a flower
Pollination: it is the transfer of the pollens
from the male part to the female part of the
flower.

12. STEPS OF THE POLLINATION
1) The petals have bright colors 
to attract insects to drink the
nectar (sugary liquid) in the
flowers.

13. 2) Pollen grains from the anther 
stick to the insects wings and gets
carried to the stigma (Pollination)

14. 3) Tube “Pollen tube” grows 
down the style and enters the
ovary

15. 4)The pollen enters the egg in 
the ovary (seeds are made)
(Fertilization)

16. 5) Then the ovary becomes a 
fruit and the petals fall.

17. A SEED’S LIFE
 Do
you think a seed is alive or
dead?
Well, A seed is alive but it waits
for the conditions to be right to
start to grow “germinate”.

18. THE CONDITIONS NEEDED FOR THE SEED
TO GERMINATE:
- For the seed to germinate it needs:
Soil
Sunlight
Water

19. GERMINATION PROCESS
A seed with a tiny
embryo inside
remains in the
ground until
conditions are right
for the seed to
germinate.
After the seed
coat splits the
embryo root
begins to grow
into the soil.
Now the
embryo can get
water
Food in the
seed feeds
the embryo as
the shoot
(stem) grows
upward the
light.
The stem
grows, leaves
develop, and
roots spread in
the soil. Now
the seedling
can make its
own food

20. SEEDS CAN BE PLANTED ALSO BY NATURE:
Nature can help in seed planting by
