Cell Wall - Definition, Function & Structure - Biology Dictionary
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.
Cell wall - Wikipedia
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]

6 days ago · Cell wall, specialized form of extracellular matrix that surrounds every cell of a plant. The cell wall distinguishes plant cells from animal cells and provides physical support and protection. Learn about the functions and chemical components of plant cell walls.
Cell Wall: Definition, Structure, & Functions with Diagram
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.
Cell Wall - Definition, Cell Wall Function, Cell Wall Layers - BYJU'S
What is a Cell Wall? A cell wall is defined as the non-living component, covering the outmost layer of a cell. Its composition varies according to the organism and is permeable in nature. The cell wall separates the interior contents of the cell from the exterior environment.
Cell Wall (Plant, Fungal, Bacterial): Structure and Functions
Mar 15, 2023 · In-plant cells, the cell wall is made up of cellulose, hemicellulose, pectin, and protein. In many fungi, the cell wall is formed of chitin and in bacteria, the cell wall contains protein-lipid-polysaccharide complexes. The cell wall has many important functions in a cell including protection, structure, and support.
The Structure and Function of a Cell Wall - ThoughtCo
Jul 29, 2024 · A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea. Animal cells however, do not have a cell wall.
Cell Wall: Definition, Structure & Function (With Diagram)
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.
