  2. Apr 27, 2017 · A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls.

  3. 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. It is primarily made up of carbohydrates like pectin, cellulose and hemicellulose.

  4. Jul 16, 2020 · The cell wall is a rigid and protective outer covering commonly found in both prokaryotic and eukaryotic organisms such as plants, fungi, algae, bacteria, and archaea, but is absent in all animal cells. It is a non-living structure that varies in color and composition depending on the type of organism, and is freely permeable to natural substances.

  5. Oct 14, 2018 · A cell wall can be defined as a rigid layer that encircles the contents of the cell. This is a semi-permeable layer that acts as a protective layer in certain types of cells. As such, the cell wall will be seen outside of the cell membrane in the cells of the following organisms: Plant cells. Fungi.

  6. The outer envelope is the cell wall and it encloses almost all cells except animal cells. Therefore, the cell wall is the outermost protective layer of the cell in plant cells, bacteria, fungal cells, and protists. It’s components vary among different organisms.

  7. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls.

  8. 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.
