NEET BIOLOGY

Detailed explanation-1: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Detailed explanation-2: -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. Xylem cells constitute the major part of a mature woody stem or root.

Detailed explanation-3: -Xylem vessels transport water and dissolved mineral ions from the roots to the rest of the plant and also provide structural support. Phloem vessels transport dissolved substances, such as sucrose and amino acids, from the leaves to the rest of the plant.

Detailed explanation-4: -Xylem transports water, minerals, and nutrients from the soil to all the plant parts. There are two types of “transport” tissues in plants-xylem and phloem. Water and solutes are transported by the xylem from the roots to the leaves, and food is transported from the leaves to the rest of the plant by the phloem.

Detailed explanation-5: -Xylem is a complex permanent tissue. It is responsible for the upward conduction of water and minerals in plants. Xylem consists of tracheids, vessels, xylem parenchyma and xylem fibres. Xylem fibres are mainly supportive in function.
