Meristemium
Meristemium, also known as the meristematic region, is a specialized area within the body of certain organisms, particularly in plants and some animals, where active cell division occurs. This region is responsible for the growth and development of the organism. In plants, meristemiums are found at the tips of roots, stems, and shoots, as well as in the vascular bundles. These regions contain undifferentiated cells that can divide and differentiate into various cell types, allowing for the elongation and thickening of plant tissues.
In animals, meristemiums are less common and are typically found in regions where tissue regeneration or growth
The study of meristemiums is crucial for understanding the mechanisms of growth and development in organisms.
