In Latin it is where we can find the etymological origin of the term cell wall. And it is that the two words that compose it derive from said language:
• Wall emanates from “paries”, which can be translated as “wall”.
• Cellular, on the other hand, is the result of the evolution of "cellullaris", which means "relative to cells" and which is composed of three distinct parts: "cella", which is synonymous with "cell"; the suffix "-ula", which is diminutive; and the suffix "-ar", which is used to indicate "relative to".
The Latin term couple derived in wall , a word from our language It has several meanings. It can be a Wall or what brings a limit to a surface or body. Mobile , meanwhile, is the adjective that indicates what is linked to the cells (the fundamental element of a living being) or that mentions a mobile phone.
The cellular wall , therefore, is what covers prokaryotic cells and plant cells . It is a rigid mantle that is located outside the plasma membrane , contributing to form the structure of the cell and providing protection to its components. It is said that the cell wall is responsible for mediation between the cell and its environment.
The peculiarities of the cell wall vary according to the organism in question. It can be a layer of chitin (in the case of fungi), cellulose (plants), peptidoglycan (bacteria) or other materials.
Specifically, in the case of plant species we could say that the cell wall has the following functions:
• It is responsible for protecting what are the contents that the cell has.
• Protects them from different diseases.
• It is responsible for regulating what is the growth of said plants, since it contains the molecules specialized in that task.
• Achieve total and absolute rigidity to what is the cellular structure.
• It provides them with a porous system that is the one that proceeds to correctly distribute the water and circulate it in the best possible way. This function must be established that it is also carried out with minerals and other substances as nutrients.
The cell walls of mushrooms they give hardness to its structure and allow to preserve the form. They also function as a barrier to prevent toxic elements from entering the fungus.
In the case of the bacterial cell wall, we would have to say that there are two types of them: gram-negative and gram-positive.
In the plants , the cell wall provides support and can be divided, depending on the species, in primary wall (which adapts to the development of the cells), secondary (the sector closest to the plasma membrane) and middle lamella (the space that links the cell walls primary of a pair of cells located contiguously).
The bacteria and the algae They also have cell walls with specific characteristics and components.
Specifically, in the case of algae we can state that its cell wall is composed of polysaccharides, cellulose or glycoproteins, for example.
