The Cell Cycle
-
-
Cell growth is accomplished by the synthesis of new molecules of proteins, nucleic acids, carbohydrates and carbohydrates.
As a cell grows larger, there is a decrease in surface area to volume ratio: therefore it is accompanied by cell division.
-
Cytokinesis
-
Usually starts during the late anaphase/ early telophase as the nuclear envelope and nucleoli are re-forming

Division in plant cells
Cannot furrow : Create a plasma membrane and a cell wall between the two daughter nuclei. Membranous vesicles from the Golgi complex align themselves across the equator. These vesicles contain polysaccharides and glycoproteins required for wall formation. Vesicles fuse together at the equator and forms a new cell wall.
The cell cycle, is the period from when a cell has been born, to when itself divides, It is a fundamental unit of time for a cell
Mitotic phase promoting factor (MPF) - Its role is to trigger the cells passage past the G2 checkpoint into the M phase
