Answer 1

Answer:

Explanation:

In simple words, the permanent tissues in a plant are those tissues that contain nondividing cells. The cells are also modified to perform specific functions in the plants.  The cells of the permanent tissue are derived from the meristematic tissue.

The permanent tissue cells are also fully differentiated. The cells are large and a definite shape and size. You can see intercellular spaces being present in between the cells. Large vacuoles are also present inside these cells. The metabolism that occurs in the cells of the permanent tissue is fairly at a lower rate.
