Roots
Stem
Flower

2. Why Plants Need Leaves Makes the food Balance the amount of water
Leaves use air, water, and the energy from the sun to make food
Balance the amount of water
Lets excess (extra) water out
Protection
Might be poisonous, sharp or tough to chew to prevent from being eaten by animals

How does a leaf help a plant live?

5. How Roots Help Plants
The root system of a plant is often below the ground
The roots help the plant
Hold it in the ground
Take in water and minerals
Store food made by the plant
Roots take in water through their root hairs, which grow deep in to the soil to capture water
Roots transport water from underground to the stems and leaves

6. Types of Roots

7. How Stems Help Plants A plant’s stems help the plant…
By holding up its leaves, flowers, and fruits
Carries food from the leaves to the roots
Stems can be thin and grow along the surface of the ground, or can wrap around the plant like a vine.
The stems of a cactus are thick and swell as they store water. The stems shrink as they lose water.
Helps them to survive in the desert.

How do stems help a plant?

10. How Flowers Help Plants
A plant’s flowers help the plant…
Make the seeds and/or pollen
Bees or other animals, or wind pollinate a flower when they move pollen to the flower part that makes seeds.
After a seed is pollinated, seeds form near the center of the flower. A fruit often grows to surround and protect the seeds.

11. Types of Flowers

12. How do seeds help the plant?
Has a tiny plant inside that can grow in to a new plant
Seed coat protects the young plant inside the seed

13. Types of Seeds

14. How do plants make new plants?
Scattering Seeds
Wind
Scatters seeds that have parachutes or wings
Water
Scatters seeds that float, such as coconuts
Carried by Animals
Scatters seeds that can stick to fur
Eaten by Animals
Scatters seeds when they eat fruit

15. Quick Quiz 1. How do flowers help the plant?
2. How do seeds help the plant?

16. What do plants need to germinate?
Right temperature
Right amount of water
Right amount of air

17. Germination Process When conditions are right…
A seed begins to sprout and a root grows from it
Stem grows from the soil and grows leaves
The leaves use sunlight to make sugar for food
Seedling becomes an adult plant with flowers
Flowers pollinate and new seeds are formed
If the seeds germinate, they grow in to new plants.

18. Life Cycle of a Plant
Seeds in fruit- the part of a peanut you eat is a seed
Germinating Seed- when a peanut germinates, a stem grows upward and a root grows downward
Seedling- as the small peanut plant grows leaves, it can begin making sugar for food
Adult plant with seeds – adult flower stalks grow downward. The peanut flowers make their seeds underground. When the adult plant dies it becomes part of the soil.

19. Life Cycle of a Plant

20. Types of Cones Cones help transport pollen and seeds
Small pollen cones
Wind blows pollen from small pollen cones to large seed cones
Large seed cones
Pollen attaches and seeds begin to grow
When the seeds are ripe they fall to the ground
Seed can grow in to a new plant

21. Types of Cones
