What is cytoplasm? »Its definition and meaning

Anonim

The cytoplasm is the element that distinguishes, par excellence, a prokaryotic cell from a prokaryotic cell. It is an element of the protoplasm, located between the nucleus and the plasma membrane, whose main function is to house the cellular organelles (basically, any structure within the cell), in this case cytoplasmic, and keep them functioning. It is divided into the ectoplasm (it is located in the peripheral zone of the cell and is in contact with the plasma membrane) and the endoplasm (it is close to the nucleus and is of higher density than the ectoplasm).

In eukaryotic cells, the cytoplasm has the smooth endoplasmic reticulum, which is characterized by not having ribosomes, intervening in the synthesis of lipids and stimulating detoxification, in addition to the rough endoplasmic reticulum (responsible for the synthesis and transport of proteins). It should be noted that, through the cytoplasm, some nutrients can pass through the cell.

The cytoplasm is made up of a cytoskeleton, thus called the fibrous structure that gives shape and a certain order to the elements within the cell and a cytosol, it is a liquid and occupies between 50% and 80% of a cell. Added to this are the organelles, which can be: ribosomes, where ribosomes are synthesized, lysosomes, whose main mission is to recycle the remains of the other organelles, vacuoles, store of proteins, Golgi apparatus, among its functions it stands out to form Primary lysosomes, mitochondria, it contains proteins and phospholipids, peroxisomes, its main function is to carry out an oxidation process that does not necessarily benefit the cell at an energy level.
