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]

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.
Definition, Cell Wall Function, Cell Wall Layers - BYJU'S
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. It also provides shape, support, and protection to the cell and its organelles.
Basic cell structures review (article) | Khan Academy
All cells have a cell membrane, but not all cells have a cell wall. Cell walls are very rigid, which makes the cell harder to move. They can be made up of a variety of substances, so cell walls in plant cells are different than those found in bacterial cells.
