1. How does light intensity affect 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 lower the light intensity, the higher the rate of photosynthesis.
  • The higher the light intensity, the lower the rate of photosynthesis.

2. How does temperature affect the rate of photosynthesis?

  • The higher the temperature, the lower the rate of photosynthesis.
  • The higher the temperature, the higher the rate of photosynthesis however temperature limits the rate of photosynthesis. Once the temperature reaches 45(degrees) the enzymes which control photosynthesis will have been denatured.
  • The lower the temperature, the higher the rate of photosynthesis.
  • The lower the temperature, the lower the rate of photosynthesis.

3. Why does a plant require magnesium?

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

4. What is the function of the palisade layer

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

5. Why does a plant require nitrates?

  • To photosynthesize.
  • To breathe.
  • To form amino acids that form proteins of cells growth.
  • To grow.
