Plant tissues are classified into two main groups, meristematic and permanent, mainly on the basis of:
1. their location
2. time of their origin during the plant life
3. capability of division
4. degree of differentiation
The meristem which occurs between mature tissues in a plant body is known as:
1. Secondary meristem | 2. Intercalary meristem |
3. Lateral meristem | 4. Cylindrical meristems |
Permanent tissues in a plant body are formed following division of cells in:
1. Primary meristems only
2. Secondary meristems only
3. Both primary and secondary meristems
4. Neither primary nor secondary meristems
