Cell wall

A cell wall is a more or less solid layer surrounding a cell. They are found in bacteria, archea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls. When a cell wall is removed using cell wall degrading enzymes, what is left of the cell and its surrounding plasma membrane is called a protoplast.

Plant cell walls have a number of functions: they provide rigidity to the cell for structural and mechanical support, maintaining cell shape, the direction of cell growth and ultimately the architecture of the plant. The cell wall also prevents expansion when water enters the cell. The term turgor is used to describe this pressure that is induced by excess water inside the plant cell. Cell walls protect against pathogens and the environment and are a store of carbohydrates for the plant.

Cell: A cell is a single unit or compartment, enclosed by a border or wall. A cell is usually part of a larger structure. More specific meanings depend on the context in which the work is used....
