a. Cell membranes (cell membrane or plasma membrane or plasma membrane)
The cell membrane and also the cell layers of wrapping the foremost half outside the cell. This membrane serves to move substances into and out of cells, as an example, regulate the entry of oxygen into the cell and regulate the discharge of carbon dioxide from within to outside the cell.
On the cell membrane of plant cells are protected by cell walls composed of cellulose and might be thickened and powerful. In animal cells there's no cell wall.
b. Protoplasm
Protoplasm is an element of the living cell, within the variety of a viscous fluid that's composed of carbohydrates, fats, proteins, mineral salts, and vitamins. Viscosity of the liquid might amendment counting on the amount of cell activity.
Protoplasm serves to manage all activities of the cell. Protoplasm consists of cytoplasm and nukleoplasma. The cytoplasm is that the fluid found outside the cell nucleus. Nukleoplasma is contained within the cell fluid within the cell nucleus.
c. Cell nucleus (nucleus)
Nucleus serves to manage the entire cell activity, particularly at the time of breeding (reproductive) cells. Nucleus to operate in protein synthesis. Nucleus is found slightly to the middle, round, have nucleoli (core child). Chromosomes within the nucleus as there are components that bring the properties to say no.
