Question

Meristematic tissues in plants are
A. Localized and permanent
B. Not limited to certain regions
C. Localized and dividing cells
D. Growing in volume

Answer 1

Hint: Meristematic tissues consist of cells that are found in growing plant areas, such as the tips of roots and stems, buds of leaves. One meristematic tissue cell remains similar to the parent cell and specialised structures are created by the others. The cells of the meristematic tissue are immature and young.

Complete answer:
A collection of related cells that play an organised role for the plant is plant tissue. For a specific function, each plant tissue is specialised and it can be combined with other tissues to make organs like flowers, stems, leaves, and roots.

-Meristematic tissues are not permanent tissue. Thus, option A is incorrect.
- Based on the region where the meristematic tissues are present, they are known as lateral, intercalary, and apical meristems. Thus, option B is incorrect.
- In plants, meristematic tissues in plants are the dividing cells that in certain specific regions are responsible for plant growth. Based on the location, meristematic tissues are categorised as apical, lateral and intercalary.
- Growth in plant length and growth in plant diameter is carried out by these cells. Thus, option D is incorrect.

Hence, the correct answer is option (C).

Note: By swift division, meristematic tissues can develop. They help in the vegetation's significant growth. Cubical, living cells with a large nucleus are the Meristematic cells. The nucleus of meristematic cells is devoid of the vacuole. There is no intercellular space in the cells. Meristem is defined as the region where these cells reside.
Meristematic cells usually have several characteristics. The cells usually have a domed mechanical shape. They are tightly packed so that there are no noticeable gaps between the cells. It has a dense cytoplasm with small vacuoles and large protruding nuclei. . Plastids are in the proplastid stage. Cellulose cell walls are thin and uniform.
