10. What is the function of the upper epidermis?
- Contains stomata, allowing O2 to diffuse into leaf and CO2 to diffuse out
- Contains a few chloroplasts- relatively transparent
- Main sight of photosynthesis
- Protective layer of leaf and barrier to harmful micro-organisms
11. What is the equation for the anaerobic respiration of yeast?
- glucose+oxygen->carbon monoxide+water
- glucose->ethanol+carbon dioxide
- glucose+oxygen->carbon dioxide+water
- glucose->lactic acid+water
12. What is the function of the palisade cells?
- Protective layer of leaf
- Main sight of photosynthesis
- Main sight of respiration
- Contains stomata
13. What is the role of the stomata in gas exchange?
- Allow CO2 to diffuse in, and O2 to diffuse out
- Allow O2 to diffuse in, and CO2 to diffuse out
- No function
- Allow spongy cells to expand and contract
14. What do magnesium ions do?

- Part of chlorophyll molecule
- Growth and repair of plant
- Make DNA
15. Which of these is an example of a protoctist?
- Chlorella
- Influenza
- Algae
- Lactobactillius bulgarius
16. What is the purpose of photosynthesis?
- To release more energy by making carbon dioxide and water
