Tissues are classified into two main groups, namely meristematic and permanent tissues on the basis of
whether the cells being able to divide or not.
position of the cells.
whether they are living or dead.
none of the above
Correct Answer :
A. whether the cells being able to divide or not.
Plant tissues are broadly classified on the basis of stages of development into two categories:
(i) Meristematic tissue - They have ability to divide.
(ii) Permanent tissue - They have lost the ability to divide.
