The meristems also influence the shapes of the mature plants since the patterns for subsequent growth are laid down in the meristems. Meristematic tissues are a group of young cells that are in a continuous state of division. The meristematic cells form permanent tissue once they lose the ability to divide. Meristematic zone: contains protoderms (epiderm), procambium (primary vascular tissue) and ground meristem (cortex and pith). Intercalary Meristem: Position: present in intercalary position in the leaves and internode; It is a part of apical meristem; It also adds to height of plants; Commonly present in monocots, grass and pines; Lateral Meristem: The apical meristem is the growth region in plants found within the root tips and the tips of the new shoots and leaves. Plants generally grow where meristematic tissue is present. At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone. The vascular plants exhibit an ‘open system’ of growth involving formation of new tissues and organs throughout its life. from your Reading List will also remove any what is lymph ?

Meristematic tissues are classified based on where they are located in the plant body. There are apical, lateral and intercalary meristems which are regions of tissue that are found in different parts of the plant that divide to produce various organs. The lateral meristematic tissues are cambium, phellogen (cork cambium), procambium, pericycle. Meristematic tissue is growth tissue and the location of most cell division. Meristematic tissue cells are either undifferentiated or incompletely differentiated, and they continue to divide and contribute to the growth of the plant. Define momentum?

The meristematic tissue can be found in three different areas: apical meristems, which are located at the growing points of both roots and stems; secondary meristems, or lateral buds, which are located at the nodes of stems where branching takes place; and within mature stems and roots, but only for some plant species. Meristematic tissues consist of three types, based on their location in the plant. (Take 10m/s^2). They are actively growing meristems that differ clearly from apical meristems and are located between more or less differentiated tissues usually at the base of each internode. Meristematic Tissue: Meristematic tissue is a tissue that is composed of cells that are capable of actively dividing and giving rise to differentiated cells in any type of tissue.
