Question

Define translocation of food in plants. How will you demonstrate that phloem is the path of tra nslocation of food

Answer 1

Because in plant phloem transport food material to the all parts of plants

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 non photosynthetic parts of the plant also require carbohydrates and other organic and non organic materials.
Translocation through phloem occurs in upward, downward, and radial directions from the source (leaves) to the sink (apices, roots, fruits, tubers etc). Chemical analysis of the phloem sap revealed the presence of sugars upto 90%.
