Question

Describe components of phloem. Define translocation.

Answer 1

Components of phloem and their functions are as follows -

1. Sieve tube − Transport food materials
2. Companion cells − Carry out the cellular functions of the sieve tube elements
3. Phloem parenchyma − Responsible for the storage of food
4. Phloem fibres − Provide mechanical strength to the cells

The process of transport of food from the leaves to the other parts of a plant is known as translocation.
