Tissues

Tissues

Tissues are groups of cells that have a similar structure and act together to perform a specific function. They are of two types: simple tissues and complex tissues. Simple tissues are made up of cells of same type or kind. E.g. Glandular tissue. Complex tissues are made up of different kind of tissues. E.g. Tissues of dry skin. Hence, simple tissue is homogeneous and complex tissue is heterogeneous.

Types of Tissues

Depending on the basis of their structure and function, tissues can be classified into four types:

1. Epithelial (Covering) tissue for protection.

2. Muscular (Contractile) tissue for movements and locomotion.

3. Connective (Supporting) tissue for binding different structures of body.

4. Nervous tissue for conduction of nerve impulses.

All the complex organisms consist of only four basic types of tissues.
