WebAt the beginning of cleavage, cell divisions tend to occur at the same time in all blastomeres, and the number of cells is doubled at each division. As cleavage progresses, the cells no longer divide at the same time. Cleavage in most animals follows an orderly pattern, with the first division being in the plane of the main axis of the egg.

WebThe cell cycle is an orderly sequence of events. Cells on the path to cell division proceed through a series of precisely timed and carefully regulated stages. In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G 1, S, and G 2 phases.
