Question

write about meristematic tissue
​

Answer 1

Answer:

A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing

Answer 2

Meristematic tissues are the cells or groups of cells that have the ability to divide. These cells divide continuously and thus helps in increasing the length and thickness of the plant. Depending upon the position, meristematic tissues can be classified as:

• ∙ Apical Meristem: It is present at the growing tips of stem and roots. It increases the length of the plant's body. The apical meristems produce three kinds of primary meristems i.e., protoderm, ground meristem, and procambium.
• ∙ Intercalary Meristem: It is present at the base of the leaves. This meristem helps in the elongation of internodes.
• ∙ Lateral Meristem: It is present at the lateral regions of the stems and roots which bring about an increase in the width of the plant body. These are of two types: cork cambium and vascular cambium.
