NEET BIOLOGY

Detailed explanation-1: -The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the center of the plant, forming a vertical column that conducts water and minerals absorbed by the roots upward through the stem to the leaves.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Phloem. The phloem is responsible for translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically active. It is made up of living cells. The cells walls of these cells form small holes at the ends of the cells known as sieve plates.

Detailed explanation-5: -The plants which store food in their stem are cactus, bamboo, pineapple, potato, ginger, onion, banana, etc. Note: The underground modification of stem is called rhizome. It is a fleshy and horizontal stem found below the surface of the soil.
