Question

what do mean by translocation of food in plants

Answer 1

Translocation of food in plants

In plants, food is prepared by the leaves by the process of photosynthesis. The food prepared by the leaves is in the form of simple sugars (glucose). No other part of the plant can prepare food. So, all the parts of a plant require food for getting energy, maintenance and growth. That is why; the food prepared by the leaves is transported to all the other parts of a plant through phloem. The transportation of food from the leaves to other parts of the plant is called translocation.

Answer 2

Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials. For this reason, nutrients are translocated from sources (regions of excess carbohydrates, primarily mature leaves) to sinks (regions where the carbohydrate is needed). Some important sinks are roots, flowers, fruits, stems, and developing leaves. Leaves are particularly interesting in this regard because they are sinks when they are young and become sources later, when they are about half grown
