Simple permanent tissues are of three types:→ Parenchyma
Parenchyma tissue is of further two types:
Epidermis having thick cuticle and waxy substances to prevent the invasion of parasites.
|These tissues consist of only one type of cells.||These tissues are made up of more than one type of cells.|
|The cells are more or less similar in structure and perform similar functions.||Different types of cells perform different functions. For example, in the xylem tissue, tracheids help in water transport, whereas parenchyma stores food.|
|Three types of simple tissues in plants are parenchyma, collenchyma, and sclerenchyma.||Two types of complex permanent tissues in plants are xylem and phloem.|
