Cell is the basic structure of life. It has three major regions the nucleus control center\”. Cytoplasm serves as a factory floor and plasma membrane the external cell barrier and acts in transport of substances. Also made out of phospholipid bilayer . Each part provides different function from the cell.

Cell is the smallest living unit which was discovered by Robert Hooke in 1965 and that it contains the genetic material, cytoplasm and plasma membrane.

The activities of cells are dictated by their structure which will then determine their function. This is according to the principle of complementarity.

The human body is made up of trillions of cells, each of which has its own specialized functions.
