Question

$What \: is \: meristematic \: tissue?$
​

Answer 1

Answer:

The meristem is a type of tissue found in plants. It consists of undifferentiated cells capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide.

Answer 2

Explanation:

Mitotic cell division happens in plant meristems, which are composed of a group of self-renewing stem cells from which most plant structures arise.

The cells of the shoot and root apical meristems divide rapidly and are “indeterminate”, which means that they are not designed for any specific end goal.

The Shoot Apical Meristem (SAM) gives rise to organs like the leaves and flowers, while the Root Apical Meristem (RAM) provides cells for future root growth.

Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces.

The apical meristem (the growing tip) functions to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.

The apical meristem is organized into four meristematic zones: (1) central zone, (2) peripheral zone, (3) medullary meristem and (3) medullary tissue.

Key Terms

meristem: the plant tissue composed of totipotent cells that allows plant growth

undifferentiated: describes tissues where the individual cells have not yet developed mature or distinguishing features, or describes embryonic organisms where the organs cannot be identified

apical: situated at the growing tip of the plant or its roots, in comparison with intercalary growth situated between zones of permanent tissue
