Apical Meristem:- It is present in the growing parts of the plant i.e. 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. The zone where these cells exist is known as the "meristem." It also adds to height of plants. How do unicellular organisms perform excretion? 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. Why translocation of food is necessary in plants? The xylem in plants are responsible for the transport of : (a) water (b) food (c) amino acids (d) oxygen.

Cell divisions and subsequent cellular enlargement in these areas lengthen the above and below ground parts of the plant. Intercalary meristems occur only in monocots at the bases of leaf blades and at nodes (the areas where leaves attach to a stem). It is known as undifferentiated tissue because cells in the meristematic tissue will eventually become vascular, ground, or dermal tissue. Cells of this tissue are very active, have dense cytoplasm, thin walls, and prominent nuclei. Apical meristems contain meristematic tissue located at the tips of stems and roots, which enable a plant to extend in length. Meristematic tissues have undifferentiated cells which form the building blocks of the specialized plant structures. Apical meristem is one of three types of meristem, or tissue which can differentiate into different cell types. The primary growth of the plant occurs in the apical meristem.
