The food is manufactured in the leaves by photosynthesis and carried out from the leaves to the other parts of the plant. The transport of food from the leaves to other parts of the plant is called translocation. It is done through a vascular tissue called phloem. The translocation of food takes place in the living cells called sieve tubes with the help of the adjacent companion cells. The translocation of food in phloem takes place by utilizing energy. The food, prepare in the leaves, is loaded into the sieve tubes of the phloem tissue using energy ATP. The water now enters the sieve tube having sugar which causes high pressure and pushes the food to all the parts of the plant having low pressure. This allows the phloem to transport food according to the plant’s needs.
