Question

based on. the tissue are divided into meristematic and permanent tissue​

Answer 1

Answer:

hope it helps you

good morning

have a good day (vv)

Explanation:

Meristematic tissue cells are either undifferentiated or incompletely differentiated; they continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing.

Answer 2

Explanation:

A cluster of cells, performing similar functions are known as tissues. In plants, tissues are classified broadly into two groups on the basis of cell division capacity, namely – Meristematic and Permanent Tissue. Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth.

Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions. Some of which is to conduct, render mechanical strength to the plant or even to carry out photosynthesis. These tissues are originated, differentiated and derived from meristematic tissues.

Difference Between Meristematic and Permanent Tissue

Following are some of the important differences between Meristematic and Permanent Tissue.
