Question

In what kind of plants do you come across ‘Kranz’ anatomy? To which conditions are those plants better adapted? How are these plants better adapted than the plants which lack this anatomy?

Answer 1

Kranz’s anatomy is found in C₄ plants; such as maize, sugarcane, etc. These plants can resist high temperatures and high intensities of light. These plants are also modified to live in an insufficient supply of nitrogen and carbon dioxide. These plants do not carry photorespiration; unlike C₃ plants. This aids in making optimum amounts of glucose. Hence, C₄ plants produce more biomass compared to C₃ plants.
