The Life Cycle of a Plant

2. Parts of a Plant

3. Parts of a Plant
Roots hold the plant in the soil so it doesn’t blow away. They also take in water.

4. Parts of a Plant
The stem holds up the plant and carries water from the roots to the leaves.

5. Parts of a Plant
The leaves use light from the Sun, carbon dioxide from the air and the water taken in by the roots to make food for the plant.

6. Parts of a Plant
The plant’s flowers make seeds.
Flower 

7. Dandelion flower and seeds.

8. Parts of a Seed Seed Coat– protects seed
Embryo (baby plant)—beginning leaves, stem and root
Cotyledon—stored food
Embryo—baby plant

9. Seeds
Seeds are formed in the center part of the flower or in the fruit. Fruits come from flowers.
Seeds come in many shapes and sizes.
Plants grow from seeds.

10. If a seed receives water and gets warm, the baby plant (embryo) inside it starts to grow.
The process of a baby plant beginning to grow is called germination. We say the seed germinates or sprouts.
The first part of the plant we see pushing its way out of the seed coat is the root.

11. Here we see pictures of a bean seed and a corn seed germinating (sprouting) and growing into plants with roots, stems and leaves.

12. Here is a speeded up picture of a bean seed germinating and growing.

13. After the seed germinates (sprouts) and grows into an adult plant, the plant flowers.
It is the flower that makes seeds for new plants to grow and develop.
This process from seed to adult plant to flower to seed is called:

14. The
Life Cycle
of a Plant

15. Life Cycle of a Bean Plant
The seeds are scattered—ready to grow.
The seed absorbs water.
The flowers make seeds.
The root pushes through the seed coat.
Life Cycle of a Bean Plant
The seedling (new plant) grows out of the ground.
The stem and its leaves grow toward the sunlight. The leaves make food for the plant.

16. Here is another diagram of the life cycle of a plant

17. Here is the life cycle of a tree.

18. How a Seed Grows into a New Plant
The life of a plant begins as a seed.
Once a seed is watered and warmed, it germinates.
The root pushes through the seed coat.
The roots of the seedling grow down into the soil and the leaves and stem push out of the ground.
The stem and its leaves grow toward the sunlight.
The leaves make the plant’s food.
The flowers form and bloom.
New seeds are formed inside the flower or within the fruit that comes after the flower dies
The seeds are scattered and wait to start growing.

This next one is a exercise on the things that are necessary for a seed to germinate.

20. Remember…
When the embryo (baby plant) inside the seed begins to grow, we say the seed sprouts or germinates.
The young plant that grows from a seed is the seedling.
The seedling grows into an adult plant and flowers.
The flowers produce seeds.

1. The parts of a plants are the

roots stems leaves flowers

23. 2. What do plants need to grow?
c _ _ _ _on dioxide from the _ _ _
w _ _ _ _
l _ gh_ from the _ _ _
carbon dioxide from the air
water
light from the Sun

24. 3. Roots of a plant take in sunlight take in water from the soil
hold the plant in the soil so it does not blow away
Both b and c

25. 4. The stem of a plant takes in sunlight takes in water from the soil
carries the water from the roots to the leaves
holds the seeds

26. 5. A plant need leaves to take in sunlight
take in carbon dioxide from the air
make food
all of the above

27. 6. The flowers of a plant take in sunlight make seeds for the plant
carry the water from the roots to the leaves
take in water from the soil

28. 6. Seeds are important to the plant because they
take in sunlight
take in water from the soil
make new plants
make food for the plant

29. Inside a seed, there is
a tiny leaf, root and stem
a flower
stored food
both a and c

30. Starting with the seed (number 1), number the plant’s life cycle in the correct order.1.

31. Congratulations!
You have learned about the parts of a plant, about seeds, and about a plant’s life cycle.
