1. Wake-up (Watch is presentation mode) 1.What is needed for photosynthesis? 1.What is produced in photosynthesis? 1.How can you tell the difference between the cuticle and the upper epidermis?

3. What does “Stomata” mean? Means “Mouth” in Greek because it allows communication between the internal and external environment of a plant.

4. Location of Stomata On the underside of the leaf on the lower epidermis

5. Function of Stomata 1.Absorb carbon dioxide required and release oxygen produced in photosynthesis

6. Function of Stomata 2. Release water through the process of transpiration.

7. Stomata Structure Guard Cells Nucleus Chloroplast Vacuole Stoma: Pore Thick Outer Wall Thin Outer Wall

9. How do stomata open and close? Turgor Pressure: Pressure exerted by water inside the cell against the cell wall

10. What is happening in the stomata? 1. The vacuole is full of water; like a full balloon 2. The turgor pressure pushes on the thin outer walls 3. Causes the guard cells to open Open

11. What is happening in the stomata? 1. The vacuole is empty; no water 2. There is no turgor pressure; no pressure on cell walls 3. The guard cells are closed Closed

12. Stomata Animation Use Headphones
