NEET BIOLOGY

Detailed explanation-1: -Xylem and phloem are known as complex permanent tissues because both of them are made up of more than one type of cells.

Detailed explanation-2: -Xylem and phloem are examples of vascular tissues. The function of vascular tissues is to conduct water and food different part of the plant body. Vascular tissues are complex permanent tissues because they are made of more than one cell type. They are derived from the differentiation of meristematic tissues.

Detailed explanation-3: -Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions. Xylem helps in conducting water and minerals.

Detailed explanation-4: -Xylem is a complex permanent, conducting tissue that conducts water and mineral nutrients in only an upward direction from root to leaves (unidirectional). It is responsible for the transport of water and minerals from roots to other parts of the plant, and it also provides mechanical support to the plant.

Detailed explanation-5: -A complex tissue is the one which has more than one type of cells having a common origin which coordinates to perform a common function. Xylem and phloem are made of different types of cells hence they are called complex tissues.
