Question

Which of the following is a pair of modified stem and modified root respectively, for food storage?

• A. Ginger and onion
• B. Turmeric and garlic
• C. Sweet potato and carrot
• D. Banana and radish

Answer 1

The correct option is D Banana and radish

Root and stem are the plant parts that arise from radicle and plumule of the germinating seed. Root generally grows towards the soil and stem grows away from the soil. Both root and stem are sometimes modified for food storage. Tap root modified to store food is seen in carrots and radish.

Adventitious root modified to store food is seen in sweet potatoes. Stem modified to store food is seen in turmeric, banana and ginger. Onion and garlic are bulbs which are modified stems and have fleshy leaves. The stem is reduced and discoid.
