Detailed explanation-1: -Living cells are organised end to end in phloem. Unlike xylem, cytoplasm is found in phloem vessels, and it passes via holes from one cell to the next. Sucrose and amino acids are transported up and down the plant by phloem. This is referred to as translocation.
Detailed explanation-2: -Organic substances such as sugars are translocated in the phloem.
Detailed explanation-3: -The phloem consists of companion cells, sieve tubes, phloem parenchyma, and fibres. The translocation of food occurs in the sieve tubes with the help of companion cells.
Detailed explanation-4: -Translocation occurs in the phloem tissue, which consists of tube-like structures called phloem vessels. These phloem vessels run from the leaves into every other part of the plant and are responsible for transporting dissolved organic solutes, such as sucrose and amino acids, from the sources to the sinks.
