Answer 1

The sun

Question 2

Photosynthesis definition

Answer 2

Photosynthesis is the process by which green plants use light energy to make glucose

  -used as a substrate for respiration
  -used to structurally build the cell wall

Question 8

What are the limiting factors of photosynthesis

Answer 8

• Temperature
  -carbon dioxide concentration
  -light intensity

Question 9

Photosynthesis summary

Answer 9

1. The light energy from the sun is trapped by chlorophyll in the chloroplasts and is converted into chemical energy which is used to generate ATP.
2. Water is split to produce hydrogen and oxygen.
3. Oxygen diffuses from the cell.
4. a series of enzyme controlled reactions, which use hydrogen and ATP (produced by the light reactions) with carbon dioxide to produce sugar.
