Regions of undifferentiated cells capable of cell division are called meristems. Meristems are present in plants and are responsible for the growth and development of new cells. The two main types of meristems are apical meristems and lateral meristems. Apical meristems are present at the tips of plant roots and shoots and promote vertical growth. Lateral meristems are found in the cambium layer of plants and promote horizontal growth. Both types of meristems continuously produce new cells that can differentiate into various cell types and contribute to the plant's growth and development.
Regions of undifferentiated cells capable of cell division are called stem cells. Stem cells have the ability to divide and differentiate into different cell types, giving rise to new cells with specialized functions. They are found in various tissues and organs throughout the body and play crucial roles in growth, development, and tissue regeneration. There are two main types of stem cells: embryonic stem cells, which are derived from early-stage embryos, and adult or somatic stem cells, which are found in specific tissues or organs of the adult body. Additionally, induced pluripotent stem cells (iPSCs) are a type of artificially reprogrammed cells that share similar characteristics to embryonic stem cells.
