Parenchyma - cells of this tissue are living & have the power of division. The celle are rounded or isodiametric. Intercellular spaces are abundent. This tissue is widely distributed in plant body.

Collenchyma - cells are living, they have the deposition of extra cellulose at the corners of the cell. Intracellular space are generally absent. This tussue is present in outer region of cortex, mid rib of leaves.

Sclerenchyma - cells are dead, their walls are greatly thickened with deposition of lignin.Intracellular space are generally absent. This tissue is found in hard structures of plants.
