These are grouped together in tissues. Some tissues contain only one type of cell. Some consist of several. The main function of meristematic tissue is mitosis . The cells are small, thin-walled, with no central vacuole and no specialized features.
Meristematic tissue is located in the apical meristems at the growing points of roots and stems.
The cells produced in the meristems soon become differentiated into one or another of several types. Protective Protective tissue covers the surface of leaves and the living cells of roots and stems. Its cells are flattened with their top and bottom surfaces parallel. The cells of parenchyma are large, thin-walled, and usually have a large central vacuole. They are often partially separated from each other.
