Permanent tissues are composed of cells that have differentiated and taken up specific roles, whereas meristematic tissue consists of actively dividing cells capable of producing new cells for growth and repair.

Permanent tissues differ from meristematic tissue in their characteristics and functions. Meristematic tissue consists of undifferentiated cells with high mitotic activity, promoting growth and development. In contrast, permanent tissues result from the differentiation of meristematic cells and are characterized by specialized structures and functions. Permanent tissues include simple tissues like parenchyma, collenchyma, and sclerenchyma, as well as complex tissues like xylem and phloem. These tissues perform specific roles in support, storage, and transport. While meristematic tissue is involved in primary and secondary growth, permanent tissues contribute to the overall structural and functional diversity of mature plant organs.
