Question

Which of the following is not correct regarding light compensation point?

• A. This condition occurs usually in evening and morning
• B. Net production is equal to respiration consumption
• C. Gross production is more than Net production
• D. There is no gaseous exchange with environment by plant

Answer 1

The correct option is A This condition occurs usually in evening and morning

• The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration.
• When the rate of photosynthesis equals the rate of respiration or photorespiration, the compensation point occurs.
  
• The compensation point is reached during early mornings and late evenings.
• Hence This condition occurs usually in evening and morning is not correct regarding light compensation point.
• So, the correct answer is 'Option A'.
