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?

Short/Brief Note

Solution

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.
