NEET BIOLOGY

Detailed explanation-1: -Xylem tissue comprises a network of dead, hollow elongated conduits such as tracheids or vessels, which may be contact with living phloem or parenchyma tissue.

Detailed explanation-2: -Xylem is a plant tissue that is complex and is responsible for water transport and nutrients to the plant. Xylem-type vessel cells can be either alive or dead. According to researchers and botanists, the elements of xylem tissue are dead except for the living parenchyma.

Detailed explanation-3: -Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants. Phloem is living tissue, responsible for transporting food and other organic materials. Xylem consists of dead cells (parenchyma is the only living cells present in the xylem).

Detailed explanation-4: -All tissues in the xylem except the xylem parenchyma are dead. Their cytoplasm is highly reduced and they only perform the function of conduction. The xylem tissues also lack cell organelles. Therefore, they are considered dead.

Detailed explanation-5: -It consists of vessels, tracheids, xylem fibres and xylem parenchyma. Except for xylem parenchyma, all other components of xylem tissue are dead. Xylem parenchyma contains parenchymatous cells having a fully functional nucleus and are capable of performing various life processes.
