During this school year, 2nd term in science class, we’ve been studying the Cells, its parts and functions, etc. Here, I am going to talk about an specific part of the cell; THE CELL MEMBRANE, and how it works in the human body.
To begin with, you need to have clear the function of a cell membrane in an animal cell :
The cell membrane forms the outer surface of an animal cell. It controls what gets in or out of the cell. In plant cells, the vacuole increases the cell surface and its crucial in maintaining the plant rigidity. According to the fluid mosaic model of Singer and Nicolson, the biological membranes can be considered as a two-dimensional liquid where all lipid and protein molecules diffuse more or less freely. This picture may be valid in the space scale of 10 nm. However, the plasma membranes contain different structures or domains that can be classified as protein-protein complexes; lipid rafts, pickets and fences formed by the actin-based cytoskeleton; and large stable structures, such as synapses or desmosomes.
In conclusion, I can say that the cell membrane is an essenrial part of the cell for our body, because as it controls the pass of substances, it protects us against disseases like infections, viruses, etc.
