Question

Is meristematic tissue found in both root and shoot apex region?

Answer 1

Answer:

Explanation:

yes they are found in both shoot and apex.

Meristematic cells in plants are divided into three types based on their positions :

APICAL MERISTEMATIC CELLS : based on their positions they are of two types:

• Apical meristematic cells : are present on the shoot and root apices. These cells are responsible for indefinite ( non stop) growth of plants.
• Axillary meristematic cells : are present on the axil (the angle between stem and leaf) . These meristematic cells form axillary bud. Axillary bud can form a branch or a flower.

INTERCALARY MERISTEMATIC CELLS : are present near the nodes and also at the base of growing branches. It helps in the elongation of internode and branches. These are also leftout apical meristematic cells.

LATERAL MERISTEMATIC CELLS: are present in region of stem and roots as circular rings.Most of the cells of lateral meristems are not present in plant from beginning, but they develop when permanent tissues undergo dedifferentiation ( conversion of matured cell into meristematic cell).

It helps in increase in the diameter or girth of the plant.

Answer 2

Answer:

There are two types of apical meristem tissue: shoot apical meristem (SAM), which gives rise to organs like the leaves and flowers, and root apical meristem (RAM), which provides the meristematic cells for future root growth. ... Apical meristems are found in two locations: the root and the stem.
