The cell: his parts and his functions


-CELL MEMBRANE: It allows the communication between the cell and his environment. It´s principal functions are: To protect the cell, to regulate the traffic of substances from the exterior and towards the interior of the cell.

-CYTOPLASM: It places between the plasmatic membrane and the nucleus. In it they find the nutrients that managed to cross the plasmatic membrane to come to the organells of the cell.


-CITOESQUELETON: He contributes to the integrity of the cell defining his form and distribution. It plays a role very importantly both in the cellular division and in the transport between cells.


-NUCLEUS: It controle the cellular physiology, the nucleus has ovoid or rounded form. It contains the DNA or genetic code.

-RIBOSOMES: Their function is to create proteins from the information that comes to him from the DNA.


-GOLGI APPARATUS: It is shaped by a set of bladders. It´s function is to store temporarily the proteins and to intervene in the processes secretores of the cell.

-MITOCHONDRIA: they never remain static; they moving across, changing form and being fused by other mitochondria. Their principal function is to provide energy to him.

-CENTRIOLO: To the set two these it is named diplosoma, and plays an important role in the cellular division (mitosis)
