Detailed explanation-1: -Cells of various types have different functions because cell structure and function are closely related. It is apparent that a cell that is very thin is not well suited for a protective function. Bone cells do not have an appropriate structure for nerve impulse conduction.

Detailed explanation-2: -These cells are different because they use the same set of genes differently. So even though each of our cells has the same 20, 000 or so genes, each cell can select which ones it wants to “turn on” and which ones it wants to keep “turned off”.

Detailed explanation-3: -A cell performs its functions with the help of cell organelles and these organelles are the subcellular components which integrate their functions and perform various life processes.

Detailed explanation-4: -Different types of cells in our bodies have different functions, and they often have different types or amounts of organelles to accomplish these specific functions.

Detailed explanation-5: -All cells are not the same because there are two very distinct types of cells that make up different living organisms: prokaryotic and eukaryotic. These cells have some aspects in common, but are quite different. Prokaryotic cells make up all bacteria and archaea, and they are always single-celled organisms.
