They are composed of cells that cease to divide. Permanent tissues are derived from meristematic tissues. These tissues form the bulk of the plant body. The cells of permanent tissues may be living or dead and small and thin walled. Cytoplasm is much less and nucleus is small and cells do not divide. There are two types of permanent tissues;
Simple tissue is made up of only one type of cells. Common simple tissues are parenchyma, collenchyma and sclerenchyma.
Complex tissue is made up of more than one type of cells working together as a unit. Common examples are xylem and phloem.
