Question: The graph below shows the relation between influence of light intensity and CO2 concentration of the rate of photosynthesis of Chlorella. Which one of the following statements explains the diagram correctly ?
- a) At low light intensity, the light dependent reaction is rate limiting but at high light intensity CO2 is rate limiting
- b) The number of chlorophyll molecules limits the rate of photosynthesis
- c) Photosynthesis is independent of light intensity provided there is no total darkness
- d) Chlorophyll responds equally to light intensities and CO2 concentration thereby limiting the rate of photosynthesis
