Very Short Question and Answers - Plant Tissues

Plant tissues are groups of cells that have a similar structure and function, working together to perform specific activities in plants.

The two main types of plant tissues are meristematic tissues and permanent tissues.

Meristematic tissue is a type of plant tissue that consists of undifferentiated cells capable of continuous division, leading to the formation of new cells.

Meristematic tissues are primarily found in specific regions of plants called meristems, which are present at the tips of roots and shoots, and in the cambium layer.

The two main types of meristematic tissue are apical meristem and lateral meristem.

Apical meristem is located at the tips of roots and shoots, responsible for primary growth, leading to an increase in length.

Lateral meristem is found in the vascular cambium and cork cambium, responsible for secondary growth, increasing the thickness of stems and roots.

Meristematic tissues contribute to plant growth by continually dividing and producing new cells that differentiate into various types of permanent tissues.

Meristematic tissue is significant as it enables plants to grow, regenerate lost parts, and adapt to environmental changes.

No, meristematic tissues are not differentiated; they are composed of young, immature cells that have the potential to become various cell types.

Meristematic cells are typically small, with thin cell walls, a large nucleus, and a dense cytoplasm, which aids in cell division.

Meristematic tissue plays a crucial role in the healing of wounds in plants by rapidly producing new cells to replace damaged ones.

Yes, meristematic tissue is found in all plants, although its distribution and activity may vary between species.

Intercalary meristems are a type of meristem found at the base of leaves or nodes in grasses, contributing to growth in length between the mature regions.

External factors such as light, water, nutrients, and temperature can influence the activity of meristematic tissue by affecting growth rates and cell division.

Yes, meristematic tissues can be cultured in laboratories for plant propagation and research purposes.

As meristematic cells differentiate, they lose their ability to divide and become specialized for specific functions, forming permanent tissues.

Primary growth refers to the increase in length of the plant body, which is facilitated by the activity of apical meristems.

Secondary growth is the increase in thickness of stems and roots, resulting from the activity of lateral meristems.

The main difference is that meristematic tissues are composed of undifferentiated cells that can divide, while permanent tissues consist of differentiated cells that have specific functions.
