Answer 2

Answer:

The modified stem in potato, ginger and Amorphophallus is concerned with three similar functions i.e. food storage, perennation and vegetative reproduction.

Explanation:

• For storage, vegetative propagation and perennation, the stem remains under the ground. They remain dormant or inactive and under favourable conditions, they give off new aerial shoots. This refers to the underground modifications of the stem.

• The asexual method of reproduction i.e. vegetative reproduction is found in plants where a part of the plant is capable to give rise to a whole new plant.
• The plants showing vegetative propagation by stems include ginger(Rhizome) and potato(Tuber) and Amorphophallus (Corm).

• All these underground stem modifications perform the function of food storage (corm, tuber) and vegetative propagation and act as the organs for perennation in plants to sustain adverse conditions.

Hence option (3) three is the correct answer.
