Permanent tissues are the tissues that have grown completely and have lost the ability to divide. The meristematic tissues divide and differentiate forming permanent tissues. Furthermore, permanent tissues are divided into simple and complex permanent tissues are Parenchyma is classified under simple permanent tissues as they are homogenous tissues, composed of a single cell type having the same structure, origin and functionality.
