2. But where does the energy come from????

3. An Introduction to Photosynthesis
Parts of a Plant
An Introduction to Photosynthesis

4. Parts Of Plant – Photosynthesis
Materials Needed by Plants for Photosynthesis:
Water, Carbon Dioxide CO2 , and Sunlight.
Materials Released by Plants in Photosynthesis:
Oxygen and C6H12O6 (Glucose).

5. Functions of the Roots
Supply plants with water and minerals absorbed from the soil.
Support and anchor the plant.
Roots store surplus food made during photosynthesis.

6. Parts of the Roots
Xylem – Brings water and minerals into the plant for
photosynthesis.
Phloem – Carries glucose from the leaves to the root cells.

7. Function of the Stem Support body of the plant.
Transport glucose and water
throughout the plant.
Some store materials.

8. Parts of the Stem Xylem – Carries water and minerals
Phloem – Glucose and minerals

9. Drawing of Stem- Including Xylem and Phloem
Xylem carries water and minerals to all parts of plant.
Phloem carries food from leaves to other parts of plant.

10. Function of the Leaves
The leaf captures sunlight and makes glucose through
Photosynthesis.

11. Parts of the Leaf
Stomata – Opens and closes to allow carbon dioxide and oxygen
in or out.
Cuticle – Waxy outer layer to prevent lose of water.
Mesophyll – Layer of leaf where photosynthesis takes place.
Cuticle
Stomata
Mesophyll

13. How do Materials Get into and Out of the Plant?
Water – Xylem
Carbon Dioxide – Stomata
Oxygen – Stomata
Glucose - Stored
