Jun 16, 2022 · Biology definition: A cell wall is a structural layer next to the cell membrane with the primary role of giving the cell rigidity and protection from mechanical stress. Its main function is to give the cell rigidity, strength, and protection against mechanical stress.
The cell wall arises as a thin cell plate formed between the plasma membranes of newly formed daughter cells after cell division. Then it matures after incorporating additional materials assembled inside the cell and secreted in the extracellular space.
A cell wall is a structural layer that surrounds some cell types, found immediately outside the cell membrane. It can be tough, flexible, and sometimes rigid. Primarily, it provides the cell with structural support, shape, protection, and functions as a selective barrier. [1]
Mar 15, 2019 · A cell wall provides an additional layer of protection on top of the cell membrane. It is found in plants, algae, fungi, prokaryotes and eukaryotes. The cell wall makes plants rigid and less flexible.
Apr 17, 2024 · In plant cells, the cell wall is a complex and dynamic structure composed primarily of polysaccharides like cellulose, hemicellulose, and pectin. It provides structural support, and protection, and facilitates communication and transport between cells.
