The fortnight Anne spent in Bolingbroke was a very pleasant one, with a little under current of vague pain and dissatisfaction running through it whenever she thought about Gilbert.
Cell wall. Many types of prokaryotic and eukaryotic cells have a cell wall. The cell wall acts to protect the cell mechanically and chemically from its environment, and is an additional layer of protection to the cell membrane. Different types of cell have cell walls made up of different materials; plant cell walls are primarily made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan.
Cell wall is found on most plant cells and fungi.Cell wall in these cells covers the cell membrane and protects it(in addition to performing several other functions-like providing mechanical strength).Cell wall in plant cells is made of cellulose,pectin,lignin and suberin while that of fungi is made of chitin.his helps enclose the cell organelles and cytosol inside the cell. the cell membrane also helps in the transfer of ions etc across from the inside to the outside of the cell as well as from the outside to the inside of the cell. a cell wall is a protective covering and it surrounds the cell membrane.
