Question
Under what conditions are C4-plants superior to C3?
✓

Answer

C4-plants can produce more sugar than C3-plants in conditions of bright light and high temperature.
It is because of the following reasons:
  1. They have a special type of leaf anatomy.
  2. They can tolerate higher temperature.
  3. They show response to high light intensities.
  4. They lack a process called photorespiration.
  5. They have greater productivity of biomass.
Many important crop plants are C4-plants including maize, sorghum, sugarcane and millet.
