How do seed plants grow & reproduce2

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 Where are seeds stored
- Water melons have flat small
seeds.
- Mangos and peaches have one
seed.
- Coconuts are giant seeds.
- 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.
-Present below the female
cones on a conifer tree.
-Produce pollens “Yellow
powder”
-Bigger cones.
-Present above the
male cone in a conifer
tree.
-Produce “make” the
seeds when the
pollens are carried by
the wind and land on
the female cone

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

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
