MAKE SURE YOU WRITE IN SENTENCES
What are the two products produced during photosynthesis?
What does the plant do with each of the products?
How can we test for each of the products?

2. The structure of leaves
Lesson 10

3. The structure of leaves
What words would you use to describe a leaf?

4. The structure of leaves
Although leaves are very thin, under a microscope, you can see that they are made up of different layers of cells
Each layer of the leaf has a different job during photosynthesis

7. The Waxy Cuticle The waterproof layer of the leaf
Parts of the leaf
The Waxy Cuticle The waterproof layer of the leaf

8. Parts of the leaf
The Upper epidermis Transparent cells that hold leaf together and let light into cells

9. Parts of the leaf
The Palisade Mesophyll Main photosynthesis layer. What organelle will be abundant in this layer?

10. Parts of the leaf
The Spongy Mesophyll Some photosynthesis and allows gases to move in and out of cells. - Sponges have holes

11. Air space Where gas exchange occurs
Parts of the leaf
Air space Where gas exchange occurs

12. Parts of the leaf
Lower Epidermis same as upper layer (Transparent cells that hold leaf together and to let light into cells)

13. Stoma (stomata) Pores or holes in leaf to let gases in and out
Parts of the leaf
Stoma (stomata) Pores or holes in leaf to let gases in and out

14. Guard cell Open and close to control the stomata
Parts of the leaf
Guard cell Open and close to control the stomata
