Cell wall is found in both prokaryotes and some eukaryotes.
In prokaryotes, such as bacteria, the cell wall is a rigid structure made of peptidoglycan that surrounds the cell membrane and provides support and protection.
In eukaryotes, some organisms such as plants, fungi, and algae also have cell walls. In plants, the cell wall is made of cellulose and provides structural support and allows cells to maintain their shape.
Some eukaryotic cells, like animal cells, do not have a cell wall, but instead have a flexible cell membrane that surrounds the cell.
