Detailed explanation-1: -Phloem is the vascular tissue which transports food from leaves to the other parts of the plant. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibers and phloem parenchyma cells. Whereas xylem transport water and minerals from roots to different parts of the plant.

Detailed explanation-2: -Phloem is the vascular tissue that transports carbon (photosynthates) from the leaves to basal parts of the plant, and vascular cambium is undifferentiated tissue responsible for secondary growth and repair of damaged phloem (Lalonde et al., 2004).

Detailed explanation-3: -The transport of food from leaves to different parts of a plant is called translocation. It takes place with the help of a complex permanent conducting tissue called phloem. Phloem transports glucose, amino acids, and other substances from leaves to roots, shoots, fruits, and seeds.

Detailed explanation-4: -Phloem: In the case of plants, the synthesized food is stored by various storage organs which include-stems, fruits, roots, etc. The vascular tissue, phloem helps in the transportation of the synthesized food from the leaves to various storage organs.

Detailed explanation-5: -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. Therefore, the vessel responsible for transporting sugars and amino acids is the phloem.
