Question

Which is not a stem modification?

• A. Rhizome of ginger
• B. Corm of Colocasia
• C. Pitcher of Nepenthes
• D. Tuber of potato

Answer 1

The correct option is C Pitcher of Nepenthes

In carnivorous plants like Nepenthes, leaves are modified into a pod which is used to attract insects and other tiny animals to fall inside and digest them. The inner walls secrete digestive enzymes that help digest the insects and extract the nitrogen needed for the plant.

Rhizome, corm and tuber are the examples of stem modification.

So the correct answer is "option c".
