The Cell
The cell can be defined as a basic functional unit of life. The term cell is derived from the Latin word and was first observed by a scientist named Robert Hook in the year 1665. All living organisms are composed of one or many cells to perform their individual functions. A cell is a smallest unit of a life, which is able to control and perform several functions in all living organisms. All unicellular organisms (single cell) including bacteria and archae, which are composed of a single cell, are examples of prokaryotic cells. All multicellular organisms (many or more than one cell) including humans, which are composed of complex or many cells, are examples of eukaryotic cells. Both prokaryotic cells and eukaryotic cells have cytoplasm, cell membrane and genetic material in common.
Is a cell necessary for a life?
Yes, all living organisms on planet earth require a cell. Cell plays a vital role in keeping us alive by controlling all types of biochemical functions inside an organism. A new cell produces through cell division of pre-existing cells.
