Cell membrane
The cell membrane is a thin living plasmid membrane surrounded by cytoplasm from the outside. Its thickness ranges from 7-8 nm. It is semi-permeable, able to separate the contents of the cell and the medium in which it is located. The cell membrane consists of two layers of phosphorylation, Which are immersed in the membrane, in addition to peripheral proteins, where the distribution of proteins irregularly, and in this article we will talk about the functions of the cell membrane.
Cell membrane components
The components of the cell membrane are characterized by mobility from one place to another; this is because the lipid molecules have the ability to switch places together, as well as the possession of the protein molecules of the same property, which explains why this membrane is called a dynamic membrane. Is attracted to the water molecule poles, which explains why it is water loving, as well as a non-polar and non-polar tail that attracts water, and therefore is not water-loving.
What are the characteristics of the cell membrane?
The cell membrane has a variety of vital properties that help it perform various functions that fit its structure. It grows with cell growth and is able to regenerate itself in areas where it is torn.
What cell membrane functions
The cell membrane is characterized by its ability to give the distinctive shape of the cell and thus preserve its contents. It regulates the exchange of different molecules and ions from the cell itself to the medium in which it lives. The cell membrane contains some structures that have many functions.
The Choices
Cysts are flexions found in parts of the cell membrane. Their primary function is to increase the surface area of the cell, increasing its absorption capacity, which is present in the intestinal epithelial cells.
Cilia
Cilia are known as short strands from which each basal body originates within the cell. Its primary function is the ability to move the cell using the adaptive harmonic movement, which is present in certain organisms such as:
Wats
Lattices are similar to cilia in terms of function and structures, but they are characterized by being longer and less numerous in the cell, and are referred to as moving helicopter movement, which are found in some organisms, such as: iglina.
Cellular wall
The cell wall is a thin, flexible cell wall that surrounds the cellular membrane of the cell. It consists of a group of bacterial substances, as well as cellulose found in the new cells, where the thickness of the cell membrane increases. This is due to the deposition of layers of other substances such as lignin, It is also known that plant cells are connected to each other by cytoplasmic filaments passing through holes located in the cellular wall.
