Transportation is a vital process in all living organism and is involved in the movement of water, minerals and other necessary nutrients to all parts of the plant. Translocation is defined as the process of transport of food from the leaves to other parts of the plant.
Phloem is mandatory for translocation
In plants, the synthesised food molecules by the leaves are transported to the different storage organs- roots, stem, fruits with the help of vascular tissue called phloem. The phloems are the complex living tissue present in all vascular plants and are mainly composed of different specialized cells called such as-companion cells, phloem fibres, phloem parenchyma cells and sieve tubes.
Listed below are a few vital functions of Phloem
- Phloem helps in translocation of food materials from the leaves to parts of the plant.
- Phloem transports food in both directions, upwards and downwards.
- ATP is required in the form of energy for transportation.
