Tissues Class 9 elaborates that all living organisms are made up of cells. When these cells bunch up and perform a similar function, they give rise to tissues. Consequently, these tissues are not the same in all organisms. Plants, for instance, are stationary. This means that their tissue composition is vastly different to that of animals.
Plant tissues are classified into two types, namely:
- Meristematic tissues
- Permanent tissues
Meristematic tissues are the tissues that are present in the region of growth, like the shoots and tips. Permanent tissues form once the meristematic tissues lose their ability to divide. Permanent tissues are further classified into 2 types, namely, simple and complex tissues.
Animal tissues can be classified into 4 types, namely:
- Connective tissue
- Epithelial tissue
- Muscular tissue
- Nervous tissue
