Cells show variety in shape !
Three types of cells having different shapes are as follows:
- Red Blood Cells
- Squamous epithelium cells
- Neurons
Functions of the cells:
1. Red Blood Cells:
- They are bi-concave shaped with an average diameter of 7.2 micro-metre.
- Their main function is transport of gases with the help of hemoglobin present inside them.
2. Squamous Epithelium Cells:
- They are flattened cells , together they attach to each other like tiles in a pavement.
- Their function is formation of tissues which line the visceras of the body (i.e. various organs).
- They allow easy diffusion of substances through them.
3. Neurons:
- They are elongated, thin, slender cells. They are the structural and functional unit of the NERVOUS SYSTEM.
- Their main function is to transport impulses from one part to another. The impulse is mainly an electrical impulse.
