These are composed of cells that are dividing continuously The cells are spherical, oval, polygonal or rectangular. The cell wall is thin and made up of cellulose. The cells are closely arranged without inter-cellular spaces. Cytoplasm is abundant and nuclei are large. Vacuoles are absent and if pr..

The cells are elongated and are circular, oval or polygonal in cross-section. Cell wall is unevenly thickened with cellulose at the corners against the intercellular spaces. Nucleus is present and hence the tissue is living. Vacuoles are small. Intercellular spaces are generally absen..
