meristematic tissue Embryonic tissue located at the tips of stems and roots and occasionally along their entire length; can divide to produce new cells; one of the four main tissue systems in plants. PICTURE ...
the growth tissue; the location of most cell division of vascular plants.
mesoderm one of three germ layers that develops to become the muscles and other internal organs.
Meristematic tissue is located in
the apical meristems at the growing points of roots and stems.
the secondary meristems (lateral buds) at the nodes of stems (where branching occurs) [View], and in some plants, ...
continues to rapidly divide producing undifferentiated cells which may eventually differentiate to form the tissue and cell types discussed above

meristematic tissue Within some seaweeds, specific tissue sites where most cell division for growth occurs.
s with dividing undifferentiated cells can sustain or renew growth indefinitely.
Parenchyma cells throughout the plant can divide and differentiate into various types of specialized cells.
Plants have meristematic tissue in several locations. Both roots and shoots have meristematic tissue at their tips called apical meristems that are responsible for the lengthening of roots and shoots.

Fibres stem usually form meristematic tissues. Cambium and procambium are their main centers of production. They are often associated with the xylem of the vascular bundles. The fibres of the xylem are always lignified.
cork cambium A layer of lateral meristematic tissue between the cork and the phloem in the bark of woody plants.
coronary arteries Arteries that supply the heart's muscle fibers with nutrients and oxygen.
[L. cortex, bark + cambium, exchange]
A cylinder of meristematic tissue in plants that produces cork cells to replace the epidermis during secondary growth.
