Where is the cell wall located?

Posted June 9, 2022


Answer

Cell walls are found in most plant cells, bacteria, algae, fungi, and some archaea. In the cells where a cell wall is present, it forms the outermost layer adjacent to the plasma membrane or cell membrane. The cell wall is a rigid semi-permeable structure made up of cellulose or chitin. It forms a barrier that encloses the cell, protecting it from harm, and regulating what substances enter and exit the cell.
