Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Tissues with active cell division
A
Permanent
B
Meristematic
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Meristematic tissues are found at the tips of the stems and roots. These kinds of meristematic tissues are known as apical meristems. The active cell division occurs at the tips of stem and root which leads to the elongation of cells that give rise to a new primary tissue.

Detailed explanation-2: -Solution: Meristematic tissues are those tissues which have cells with active cell division capacity. Simple tissues are those tissues which have all the cells similar in structure and function.

Detailed explanation-3: -The meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. The different types of meristems are apical, lateral and intercalary meristems.

Detailed explanation-4: -Final Answer: Thus, the tissue which perpetuates itself by active cell division is meristematic tissue.

Detailed explanation-5: -Apical Meristem Various cell divisions facilitate the growth of the cells in the roots and shoots and help in cellular enlargement. Apical meristem is divided into-promeristem zone, which contains actively dividing cells, and the meristematic zone, which contains protoderm, procambium and ground meristem.
