Detailed explanation-1: -Translocation is the movement of materials in plants from the leaves to other parts of the plant. Nutrients, mainly sugars, are created in the leaves during photosynthesis. These are then transported throughout the plant through phloem, which are a long series of connected cells.
Detailed explanation-2: -Translocation occurs through part of vascular tissue known as phloem that also transports carbohydrates, amino acids and other substances such as plant hormone which are made in tips of roots and shoots to the storage and growing organs.
Detailed explanation-3: -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.
Detailed explanation-4: -(b) The transport of food from the leaves to the other parts of the plant is called translocation.
Detailed explanation-5: -(1) The transportation of food from the leaves to other parts of the plant occurs in the vascular tissue, namely the phloem. This process of transporting food is known as translocation. The phloem consists of companion cells, sieve tubes, phloem parenchyma and fibres.
