Write Some Characteristics Of Meristematic Tissue and Incident Ray?
Answers
The characteristics of meristematic tissue are as follows:
- The cells of these tissues are commonly called meristems.
- The meristematic tissue has the quality of self-renewal.
- They have very small and few vacuoles.
- The meristematic tissue is living and thin-walled.
- The protoplasm of the cells is very dense.
The incoming light ray is called the incident ray. The light ray moving away from the surface is the reflected ray. The most important characteristic of these rays is their angles in relation to the reflecting surface. These angles are measured with respect to the normal of the surface.
Explanation:
The cells of these tissues are commonly called meristems.
The meristematic tissue has the quality of self-renewal. Every time the cell divides, one cell remains identical to the parent cell, and the others form specialized structures.
They have very small and few vacuoles.
The meristematic tissue is living and thin-walled.
The protoplasm of the cells is very dense.
The meristematic tissues heal the wounds of an injured plant.
The cells of the meristematic tissue are young and immature.
They do not store food.
They exhibit a very high metabolic activity.
They possess a single, large and prominent nucleus.
