The name eukaryotic cell is applied to all cells of a living organism that have a membrane that covers and protects them from the outside environment , but especially for having a cell nucleus defined and delimited inside the cell by a protective layer or nuclear membrane.
Eukaryotic cells differ from other types of cells, for example, prokaryotic cells, of which there is also a nucleus, but which are not covered by any membrane or envelope which is found scattered throughout the cell.
Eukaryotic cells are present in most living beings on the planet, since their composition allows us to talk about both tiny beings and the world’s most giant mammals and animals
They all have this type of cell. On the contrary, prokaryotic cells are only present in organisms known as bacteria and archaea, which are much simpler although they reproduce more easily.
For experts, the distinction between prokaryotic and eukaryotic cells thousands of years ago was one of the reasons why life has become more complex and advanced.
Inside the eukaryotic cell we find the cytoplasm, which is an emulsified liquid that is present in different parts of the cell, including the nucleus
Cytoplasm is something like the placenta of a pregnant woman , as without it the different elements of a cell could not survive.
The plasma membrane is the one that covers the set of cytoplasm and other elements of a cell, protecting them and separating them from the external environment. In the cytoplasm we find the cell nucleus, which in turn is covered by a membrane or nuclear envelope, which protects and differentiates it from the rest of the cell’s parts.
The nucleus is the most important part of a cell, as it houses the material or genetic information that will make the living being what it is and not something else. This information is reproduced in the same way in all cells of the living being and is what determines from the moment of its birth until its death.
