1. What is the function of the spongy mesophyll

  • Cells contain lots of air spaces which are connected to the stomata which allow optimum exchange of gases
  • Transparent to allow sunlight through to other layers.
  • Contain guard cells which regulate the opening and closing of the stomata.
  • Cells towards the top of the leaf contain chloroplasts which allow maximum absorption of sunlight

2. Why does a plant require magnesium?

  • To create chlorophyll for photosynthesis.
  • To create cells for photosynthesis.
  • To heal the plant.
  • To make the plant stronger.

3. How does CO2 concentration affect the rate of photosynthesis?

  • The lower the concentration of CO2, the higher the rate of photosynthesis.
  • The lower the concentration of CO2, the lower the rate of photosynthesis.
  • The hgiher the concentration of CO2, the higher the rate of photosynthesis however CO2 limits the rate of photosynthesis. After a certain point the increase of CO2 has no further effect.
  • The higher the concentration of CO2, the lower the rate of photosynthesis.

4. How does light intensity affect the rate of photosynthesis?

  • The lower the light intensity, the higher the rate of photosynthesis.
  • The lower the light intensity, the lower the rate of photosynthesis.
  • The higher the light intensity, the higher the rate of photosynthesis however light intensity limits the rate of photosynthesis. After a while the light intensity has no further affect on the rate of photosynthesis
  • The higher the light intensity, the lower the rate of photosynthesis.

5. Give another adaptation for photosynthesis

  • Their shape
  • Leaves contain chlorophyll which are inside millions of chloroplasts to allow absorption different parts of the spectrum.
  • Tall
  • Because they are green
