The main three theories are that - all organisms are composed of cells- the cell is the basic unit of structure and organization in organisms- All cells come from pre-existing cells
The parent cell divides into two "daughter" cells. This will repeat over and over, and this is what we define as the cell cycle!
Fun Fact: Each stage of the cell cycle, such as G1 (Growth/Gap 1), Synthesis/ Stage, then G2/ Gap 2 stage, then following mitosis, has their own checkpoint! These checkpoints review/ revise what the cell has done during the stage.
