The living component of xylem tissue?

A. Xylem parenchyma
B. Xylem tracheid
C. Xylem vessel
D. Xylem fibre

Only the xylem parenchyma is living, the answer is A.

To determine the living component of xylem tissue, we need to understand the composition of xylem tissue and the characteristic features of its different components. Xylem tissue is a complex plant tissue that is responsible for conducting water and minerals from the roots to the rest of the plant. It is made up of four main types of cells: xylem parenchyma, xylem tracheids, xylem vessels, and xylem fibers.

Among these four types of cells, the living component of xylem tissue is xylem parenchyma. Xylem parenchyma cells are living cells that are involved in various physiological functions, such as storage, lateral conduction of water, and providing mechanical support. These cells have thin cell walls and large intercellular spaces, allowing for the transport of water and dissolved substances.

To recap, the living component of xylem tissue is xylem parenchyma.
