1. Simple epithelium is composed of one layer of cells, while compound epithelium is composed of more than one layer of cells. 

2. Cardiac muscles are present in the cells of heat only. They have contractile property which helps in the pumping action of the heart. Striated muscles are present near articulatory joints. Their role is to facilitate movement of organs like hands and feet.

3. Dense Connective Tissue. Fibers and fibroblasts are compactly packed in the dense connective tissues. Orientation of fibers show a regular or irregular pattern and are called dense regular and dense irregular tissues. In the dense regular connective tissues, collagen fibers are present in rows between may parallel bundles of fibers.

Tendons, which attach skeletal muscles to bones and ligaments which attach one bone to another are examples of this tissue. Dense irregular connective tissue has fibroblasts and many fibers (mostly collagen) that are oriented differently. This tissue is present in the skin.

4. Adipose tissue is a type of loose connective tissue located mainly beneath the skin. The cells of this tissue are specialised to store fats. The excess of nutrients which are not used immediately are converted into fats and are stored in this tissue. Blood is a fluid connective tissue. The main function of blood is to transport gases, nutrients and waste products in the body.

5. Simple gland is composed of single cell, while compound gland is composed of multiple cells.
