The cell is the fundamental unit of structure and function in living organisms.2. All cells arise from pre-existing cells by division.3. Energy flow (metabolism and biochemistry) occurs within cells.4. Cells contain hereditary information (DNA) which is passed from cell to cell during cell division.5.
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. 1  During interphase, the cell grows and makes a copy of its DNA. 2  During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
