NEET BIOLOGY

Detailed explanation-1: -Photosynthesis is not a primary function of stem. The process by which leaves prepare their food in the presence of sunlight by using water and carbon dioxide is called photosynthesis.

Detailed explanation-2: -(i) It supports branches, leaves, flowers, and fruits. (ii) It transports water and minerals from the roots to the leaves and other parts of plants. (iii) It transports food from leaves to different parts of the plant. (iv) It holds the plant upright.

Detailed explanation-3: -Yes, if the stem is green and contains chlorophyll, it can prepare food for the plant. While most photosyntesis takes place in the leaves, some photosynthesis takes place in the stem too.

Detailed explanation-4: -The stem is the part of the plant which develops from the shoot after germination. Its main function is to help in the movement of water which is absorbed by the roots to different parts of the plant. The stem provides support to the plant and helps in keeping the plant erect.

Detailed explanation-5: -The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
