Meristem | Definition, Function, Types, Examples, & Facts
Meristem, region of cells capable of division and growth in plants. Meristem cells are typically small cells the diameters of which in different directions are about equal. They have a dense cytoplasm and relatively few small vacuoles (watery saclike enclosures).
Meristem - Wikipedia
In cell biology, the meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until they become differentiated and lose the ability to divide.
