The cytoplasm is a colloidal dispersion, a granular fluid, found inside the cell, between the cell nucleus and the plasma membrane. It is part of eukaryotic cells and prokaryotic cells.
The cytoplasm is composed of the cytosol or cytoplasmic matrix, the cytoskeleton, and organelles. It also contains several nutrients that, once they have crossed the plasma membrane to reach the organelles.
For this reason, various and important molecular reactions are carried out in the cytoplasm for the functioning of the cell.
The cytoplasm is of utmost importance in the structure of the cell, it constitutes its interior part, it shapes it, it provides mobility and it allows various metabolic reactions important for its proper functioning to take place.
The main function of the cytoplasm is to contain cell organelles and allow their movement. These include ribosomes, lysosomes, vacuoles and mitochondria, each of these organelles has a specific function and some may have a certain amount of DNA.
Likewise, the cytoplasm allows these organelles to replicate in cases where cell division takes place and protects the percentage of DNA it contains.
The movement of the cytoplasm contributes to the movement of the nutrients that have been concentrated in this colloidal dispersion, whether modified or compounded, and that produce energy that is released. This energy also enables the cell to move.
On the other hand, the cytoplasm also enables cellular respiration, which allows its survival and functioning.
