Cell (biology) The cell is the structural and functional unit of all living organisms, and is sometimes called the building block of life.. Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100 trillion cells; a typical cell size is 10 Âµm, a typical cell mass 1 nanogram). The largest known cell is an ostrich egg.
All living things called organisms have something in common. All organisms, from the smallest to the largest, are all made of cells. A cell is the basic unit of life. It is the smallest unit (or building block) of a living organism that is capable of life. A cell is the smallest unit of living matter there is and each one must be able to carry out the processes of life. Within cells, there are structures that work together to allow the cell to live.
