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. In plant biology, the term "meristematic tissue" refers to the living tissues containing undifferentiated cells that are the building blocks of all specialized plant structures. The apical meristems are the tissues located at the growing tips of the developing root and shoot of the plant. 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. It is a part of apical meristem.
