meristem

or

meristematic tissue

a region of a plant in which active cell division (MITOSIS) occurs, the cells of the meristem not being differentiated into a specialist form. Meristematic tissues occur at the root and shoot tips (see APICAL MERISTEM giving growth in length, while increase in girth of the plant is produced by the CAMBIUM of VASCULAR BUNDLES and the INTERFASCICULAR CAMBIUM. Note that such specialist dividing zones are not found in animals, where cell division occurs in most tissues.

Representative shoot apices of each class were preserved for microscopic analysis to assess the degree of floral initiation or panicle development of the shoot apical meristem. For microscopy, the shoot apices were vacuum infiltrated overnight with a standard formalin-based fixative consisting of 100 mL/L formalin, 50 mL/L acetic acid and 500 mL/L ethanol in 350 mL/L water, dehydrated in a graded alcohol series, embedded in paraplast, sectioned at 8-[micro]m thickness, and stained with 10 mL/L Toluidene Blue-0 at pH 4.5.
Early in development, the shoot apical meristem produces only leaves, each of which develops a meristem in its axil.
