1. PLANTS

2. Plants are living things that, like animals, need basic things to live.
Air – contains carbon dioxide
Nutrients – substances such as minerals
Water
Light – no plant can live in total darkness

3. The big difference between plants and animals is that plants can make their own food.

4. Making Food
A plant makes its own food by a process called photosynthesis that takes place in a plant’s leaves.

5. A plant needs four things for photosynthesis:
Sunlight
Water – gathered by the roots from soil
Carbon dioxide – from the air
Chlorophyll – material that makes a leaf green

6. Photosynthesis
Plants use sunlight to turn the water and air into glucose (sugar). Plants use glucose as food for energy. Oxygen is then given off as a waste product from the leaves.

7. Oxygen is given off as waste, like smoke from a factory’s smokestack.

8. Functions of Plant Parts

9. Carry on photosynthesis
Leaves
Carry on photosynthesis
Release oxygen

10. Stems Support plants and give them shape
Contain tubes that carry water and minerals from the roots and food from the leaves to all parts of the plant
Store water and food

11. Roots
Hold plants in the soil
Take in water and nutrients

12. Plant Life Cycles
Seeds are the first part in a flowering plant’s life cycle.

13. To begin to grow, seeds need warmth, water, and air.
This helps it to germinate (sprout)
Seedlings sprout in soil and grow to become mature (adult) plants.
Mature plants form flowers.

14. Flower Parts and Seeds
Flowers have parts that work together to make seeds.

15. Stamen
Makes pollen (a kind of powder)

16. Pistil The top collects pollen
The bottom is the ovary where seeds form – the ovary swells up
