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 phloem. It also produces the Ground meristem: develops Shoot Apical Meristem Apical Meristems:. The apices of stem and root are called as growing points. They are occupied by meristematic tissues.

They undergo active MITOSIS when growth is occurring (depending on the season) and the new cells look similar to the The aerial structure of higher plants derives from cells at the tip of the stem, in the shoot apical meristem (SAM). Throughout the life of a plant, the SAM produces stem tissues and lateral organs, and also regenerates itself. For correct growth, the plant must maintain a constant flow of cells thr … The apical meristem consists of upper promeristem and lower primary meristem. In primary meristematic region the cells are differentiated into three fundamental units.
