Web15 de jun. de 2024 · Meristem. In plants, the meristem is the area of tissue from which new growths are formed. At the meristem, the plant cells are continually proliferating and are not yet differentiated. Depending on where on the plant the meristem is, and on which signals it receives, the meristem tissue can give rise to new leaves, flowers, or roots. Apical meristems are the completely undifferentiated (indeterminate) meristems in a plant. These differentiate into three kinds of primary meristems. The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are … Ver mais 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 … Ver mais Apical meristems may differentiate into three kinds of primary meristem: • Protoderm: lies around the outside of the stem and develops into the epidermis. • Procambium: lies just inside of the protoderm and develops into primary xylem and primary Ver mais Under appropriate conditions, each shoot meristem can develop into a complete, new plant or clone.
