Question

Which of the following is wrong about xerophytes?

• A. Sunken stomata
• B. Small spiny leaves
• C. Thick cuticle
• D. Large number of stomata

Answer 1

The correct option is D Large number of stomata

Xerophytes show structural adaptations to discourage water loss through transpiration and increase water absorption. Such, adaptations include small spiny leaves, thick waxy cuticle on leaf surface, sunken stomata and well developed vascular tissue. Leaves show reduction in number of stomata to cut off transpiration losses of water. Also some succulents show 'Crassulacean Acid Metabolism (CAM)'. Their stomata open only during night.

Thus, the correct answer is option D.
