Plant Tissues
Plant tissues are basically of two types : meristematic and permanent. This differentiation is based on the ability of the mature cells of the tissue to divide and produce new cells. Meristematic tissue cells are capable of dividing, while permanent tissue cells are not.
Meristematic Tissue:
This tissue consists of actively dividing cells and is present in the growing regions of plants, e.g., the tips of roots and stems. The cells can be round, oval, polygonal or rectangular, but there are a few things they have in common. They are packed closely without inter-cellular spaces, have thin cellulose walls, dense cytoplasm and prominent nuclei. Vacuoles are almost absent in such cells because they are completely filled with sap. There is more than one way of classifying meristematic tissue
1. On the Basis of Origin, meristems (meristematic tissue) are of two types primary and secondary. The former are derived directly from the meristems of the embryo. The latter develop later in the life of the plant from permanent tissues.
2. Based on the Position in the plant or depending on the region of the plant where it is present, meristematic tissue can be of three types—apical, lateral and intercalary. In case of the roots due to the presence of root cap the growth of root occur sub apically.
