Question

The plant stores food in the stem in
A. Bryophyllum
B. Banana
C. Brinjal
D. Cucurbita

Answer 1

Hint: Plants can produce their own food by photosynthesis. The product glucose forms a polymer called starch which can be stored in stems, roots, leaves, fruits, and seeds of a plant.

Complete answer: Solar energy is “fixed” by the green plants by the photosynthetic process. Upon receiving the photon, photosynthesis starts. By this carbon dioxide and water react to form glucose and oxygen. This is how plants and some other photosynthetic organisms produce their own food.
Plants store their food in the form of starch in various parts of them. Starch is a polysaccharide of glucose monomers. Glucose residues are linked by glycosidic bonds. This starch can be stored in the leaves, stems, roots, flowers, fruits, and seeds of a plant. The plants which store food in their stem are cactus, bamboo, pineapple, potato, ginger, onion, banana, etc.

So, the correct option is B. Banana

Note: The underground modification of stem is called rhizome. It is a fleshy and horizontal stem found below the surface of the soil. In these, some small nodes and internodes are found. The nodes/internodes are covered by scaly leaves.
