NEET BIOLOGY

Detailed explanation-1: -The food which is prepered by the leaves of the plants during photosynthesis needs to be transported to other parts like stem, roots, fruits and flowers. The plant tissue responsible for this transport of food material is called phloem tissue.

Detailed explanation-2: -The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

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 transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure.

Detailed explanation-5: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.
