Question

Which is a C₄ plant?

• A. Cotton
• B. Maize
• C. Wheat
• D. Rice

Hint:

C4 plants are more efficient in hot and dry environments compared to C3 plants because they minimize water loss and photorespiration, which is why maize, sugarcane, and sorghum are considered C4 plants.

Answer 1

The Correct Option is B

C₄ plants are characterized by their unique photosynthetic process, which enables them to thrive in areas with high temperatures and intense sunlight. They utilize a specialized mechanism to initially bind carbon dioxide into a four-carbon compound, hence the name C₄.

The options available are:

• Cotton
• Maize
• Wheat
• Rice

The correct answer is Maize. Maize is a classic example of a C₄ plant, which carries out C₄ photosynthesis that provides an adaptive advantage in hot climates by reducing photorespiration and increasing water-use efficiency.
