Question 1

What is the word equation for photosynthesis?

Answer 1

carbon dioxide + water -> glucose + oxygen

Question 2

What are 4 leaf adaptations?

Answer 2

1. stomata and guards cells control gas exchange
2. thin leaf shape reduces distance of diffusion
3. spongey mesophyll layer is moist, dissolving gases and speeding up diffusion
4. air spaces increase SA for diffusion.

Answer 3

gain

Question 4

Answer 4
