AP BIOLOGY

Detailed explanation-1: -Meristematic tissue or meristem consists of cells that have the capacity to continue dividing indefinitely. They are found in the growing parts of the plant, such as root and stem apices, and cambium in roots and stems.

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: -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. The cells actively divide to produce new cells. Meristematic cells may be intercalary as in case of monocots.

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.

Detailed explanation-5: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
