Detailed explanation-1: -Final Answer: Thus, the tissue which perpetuates itself by active cell division is meristematic tissue.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Meristematic cells have immense potential to divide. For this purpose, they have dense cytoplasm and thin cell wall. Vacuoles possess cell sap and provide rigidity and turgidity to the cell. This might pose a problem for cell division.
