The tissue is defined as a group of cells which perform a particular function. The tissue which is composed of immature and undifferentiated cells which are either in a continuous state of division or retain the power of division is known as meristematic tissue. The tissue which is composed of mature and differentiated cell that has undergone definite growth and has definite size, shape and function is known as permanent tissue.
