Detailed explanation-1: -stem, in botany, the plant axis that bears buds and shoots with leaves and, at its basal end, roots. The stem conducts water, minerals, and food to other parts of the plant; it may also store food, and green stems themselves produce food.
Detailed explanation-2: -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. The stem of the cactus plant synthesizes its own food because there are no leaves.
Detailed explanation-3: -A stem performs the following functions in a plant: (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.
