Mature and differentiated cells formal meristematic / permanent) tissue.
Answers
Explanation:
Correct option is
D
The cells of permanent tissues divide further.
Permanent tissues may be defined as a group of living or dead cells formed by meristematic tissue and have lost their ability to divide and have been permanently placed at fixed positions in the plant body. Meristematic tissues that take up a specific role lose the ability to divide. This process of taking up a permanent shape, size and a function is called cellular differentiation. Cells of meristematic tissue differentiate to form different types of permanent tissues.
Simple tissues - A group of cells which are similar in origin; similar in structure and similar in function are called simple permanent tissue.
Answer:
(i) Plant tissues are classified into two types:
(a) Meristematic tissue
(b) Permanent or non-diving tissue.
Tissues made up of actively dividing cells are called meristematic tissues or meristems.
Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches.The cells present in these tissues constantly divide to produce new cells.This leads to an increase in the height and girth of plants.Meristematic tissues are characterised by the following features:
The cells actively divide to produce new cells.
The cells are generally small and the cell walls are thin.
The cells have large nuclei and vacuoles are absent.
