Meristematic Tissue Definition
“Meristematic tissue is the plant tissue that has the ability to divide actively throughout its life.”
What is Meristematic Tissue?
Carl Wilhelm von Nägeli coined the term “meristem.” Meristematic tissue contains undifferentiated cells, which are the building blocks of the specialized plant structures.
Meristematic tissues contain living cells with varied shapes. They possess a large nucleus devoid of the vacuole. The cells have no intercellular space. The zone where these cells exist is known as meristem.
The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. These cells help to increase the length and girth of the plant.
Let us have a detailed look at the characteristics and types of meristematic tissue.
Characteristics of Meristematic Tissue
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. 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
