Differentiate between parenchyma, colenchyma and sclerenchyma - Get the answer to this question by visiting BYJU S Q&A Forum. Epithelial tissue always has an exposed outer surface and an inner surface anchored to connective tissue by a thin, non- cellular structure called the The walls of the sclerenchymatous cells are thickened and have narrow lumen. Fibres are abundantly found in many plants. These tissues are usually not rigid since the cells do not have cell walls. For example, in Amoeba, a single cell carries out movement, intake of food and respiratory gases, respiration and excretion. There are no inter-cellular spaces between sclerenchyma cells.
