(i) They act as supporting and packing tissue as they are found between visceral organs.
(ii) They help in the repair of tissue.

(i) To avoid infection, SavlonlDettol is disinfectant.

Difference between Striated and Unstriated Muscles

Fibrous connective tissue. It is of two types:
(i) The white fibrous connective tissue,
(ii) Yellow fibrous connective tissue.
(i) The white fibrous connective tissue consists of white, nonelastic, unbranched fibres which unite to form bundles called tendons. Tendons are strong, tough and smooth, rope-like structures that serve to attach muscles with the bones.
(ii) The yellow fibrous connective tissue. It also consists of fibres which are fine thread-like structures. These fibres are quite elastic. Like white elastic fibres, these fibres also form cords called ligaments. These ligaments connect two bones.

Epithelial Tissue. Epithelial tissue forms covering of entire surface of the body and lines the internal organs. Because of this epithelial tissue is also called protective tissue. It also forms a barrier to keep different body system separate. In this tissue cells are closely associated and arranged on a very thin extracellular fibrous basement membrane. Epithelial tissue may be composed of one (simple epithelium) or more layers of cells (compound epithelium). The skin, lining of mouth and alimentary canal, lung alveoli etc. are made of epithelial tissues.

Collenchyma. The cells in this type of tissue are living, elongated and thickened with cellulose at the corners. There is very little intercellular space. This tissue provides flexibility and mechanical support to plants. This tissue is found in hypodermis of stems and leaf stalks.

The cells of meristematic tissue lose the ability to divide and get differentiated into specialised cells. These differentiated cells from different types of tissues which are known as permanent tissues. Some examples of permanent tissues are parenchyma, sclerenchyma, etc.

(i) This tissue consists of actively dividing cells.
(ii) This tissue is present in growing regions of plants.
(iii) In this tissue, cells are packed closely without intercellular spaces.
(iv) Cells of this tissue have thin cell walls, dense cytoplasm and prominent nuclei.
