Meristemoid

from Wikipedia, the free encyclopedia

The term meristemoid describes meristematic cell groups or single cells that are ultimately converted into permanent tissue .

Small nests of actively dividing cells are often found in the differentiation zones of shoots and leaves , but they do not contain stem cells . The cells of such meristemoids therefore ultimately all become permanent cells, which, however, differ in shape and function as idioblasts from the other cells of the tissue . From meristemoids go e.g. B. stomata and multicellular hair. The leaf systems at the apex are ultimately meristemoids, which is expressed in the limited growth of the leaves. Meristemoids are often derived from single cells that have resulted from inequitable division.
