Question

Suppose we conduct an experiment to demonstrate respiration in a green plant. What
special precaution is required to be taken in it?

Answer 1

The following precaution can be considered:

• Plant should be covered or kept in dark as the photosynthetic rate is higher in normal
  light than respiration. Hence the carbon dioxide that is generated by respiration would be
  used up by photosynthesis making it difficult to detect carbon dioxide. This is why
  photosynthesis is required to be stopped hence plants are kept in darkness.
