A living cell is composed of cell organelles that make it to function normally. Cell organelles include structures like the nucleus and the nucleolus, rough and smooth endoplasmic reticulum, cytoskeleton, ribosome, Golgi vesicles, mitochondria, vesicles, lysosomes, centrioles and cell membrane. The above structures functions together in different ways to enable the cell to divide, grow, metabolize, create new cells and produce proteins (Wilson 2004).
Functions of the membrane are to protect the cell from its surrounding and to enable it to function normally without distorting its electric capability to synthesize DNA, protein and lipids.
The cytoskeleton holds the cytoplasm that organizes and maintains the shape of the cell besides maintaining the cell organelles in place. It also helps to control intake of outside materials in the cell (endocytosis).The cytoskeleton also helps during cell division when the daughter cells separate in anaphase 1 and 2 .it is through this cytoplasm that the cell components are moved in the process of cell growth and mobility.
