To begin with, a zygote is formed by the union of ova from the female of the species and the sperm of the male. A zygote is a complete cell. Thereafter, this particular cell divides to form other cells by a process is known as cell-division.

Cells are formed by a process called cell-division. In the cell division, a cell splits to form two daughter cells. When the division is over, each daughter cell has the same kind of genetic material as the parent cell and has roughly half of its cytoplasm. Cell-division is also known as "cell doubling." It is the process by which cells multiply to form more cells.

Cell division is the biological foundation of life. For simple unicellular organisms, one cell divides to form an entire organism. On a bigger scale, cell division can create progeny from multi-cellular organism, for instance, in case of plants that grow from cutting. Mitosis and meiosis are the two types of cell-division.

The cell basically is a structural and practical unit available in all living organisms, and at times is known as "building block of life". The cell theory was initially created in the year 1839 by Matthias Jakob Schleiden and Theodor Schwann, it stated that all organisms are made up of one or more cell or cells and that all cells come from pre-existing cells. Fundamental function of an organism take place inside the cells, and all cells have in them hereditary information essential for regulating cell functions and for sending out information to the next production of cells.

Each and every cell somewhat self-contained and is also self-maintained, it consumes nutrients and transforms these nutrients into energy. Each cell saves in it a particular set of orders for executing each of these actions.
