P. University) and has many years of experience in teaching. The secondary walls of the matured sclerenchyma cells are densely thick and contain lignin and hemicellulose. 3. Columnar Epithelium For example, in Amoeba, a single cell carries out movement, intake of food and respiratory gases, respiration and excretion. They are loosely packed and have large intercellular space (space between the cells). Complex tissues are made of more than one type of cells. Ø Sclerenchyma is a simple permanent tissue in plants. The cells of collenchyma are living and have the cytoplasm and the nucleus. CBSE NCERT Solutions for Class 9 Science Chapter 6 . Meristematic tissue. Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. Tissue that connects muscle to bone in humans. These are generally rigid woody cells with a compact arrangement. See more. Differentiate between parenchyma, colenchyma and sclerenchyma - Get the answer to this question by visiting BYJU S Q&A Forum. They are long and narrow as the walls are thickened due to lignin, such cell walls are called lignified.
