A meristem is the tissue in all plants consisting of undifferentiated cells and found in zones of the plant where growth can take place.

meristem - a region of rapid mitosis, which produces the new cells for root growth.
root cap - a sheath of cells that protects the meristem from abrasion and damage as the root tip grows through the soil.
meristem -- Group of undifferentiated cells from which new tissues are produced. Most plants have apical meristems which give rise to the primary tissues of plants, and some have secondary meristems which add wood or bark.
meristem
(mare-eh-stem) [Gk. merizein, to divide]
Plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth.
meroblastic cleavage ...
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 ...
meristem. The collection of cells at the growing point of a plant that are capable of cell division.
metamorphosis. The change in form that takes place as insects grow from immatures to adults.
meristem
A region of a plant in which active cell division occurs, the cells of the meristem being undifferentiated into a specialized form. Meristematic tissues occur at the root and shoot tips giving growth in length.
apical meristem A meristem (embryonic tissue) at the tip of a shoot or root that is responsible for increasing the plant's length.
meristem The tissue or zone from which new cells are produced by cell division.
meristematic tissue Within some seaweeds, specific tissue sites where most cell division for growth occurs.
Roots are further broken down into the primary root and lateral roots that each has apical meristem at their tips. Root hairs are also a common structure on roots.
Plants, however, have an apical meristem located at the tip of every root and stem that remains totipotent. They have other meristems that are also totipotent.
They are characterised by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localised regions of cell divisions (meristems); cellulose within cells providing rigidity; the absence of organs of locomotion; ...
All plastids develop from tiny organelles found in the immature cells of plant meristems (undifferentiated plant tissue) termed proplastids, and those of a particular plant species all contain copies of the same circular genome.
