The first Web site built was at CERN and was first put online on 6 August 1991 by Timothy John Berners-Lee.The first website was info.cern.ch. It was an internal page used at CERN, where Tim Berners Lee invented HTML. By the way, the Internet was created long before the 90's, it first appeared in 1969 as a DARPA project. The Web came in the 90's.
Cell walls can be composed of polysaccharides, proteins, lipids, or a combination of these. Cell walls provide increased mechanical strength and resistance to lysis by osmotic shock (water moving into the cell). Cell walls are found in the cells of eubacteria, archaebacteria, fungi, algae, and plants.The cell walls vary greatly in their compositions: 1  Eubacteria. 2  Almost all eubacterial species have cell walls containing a polysaccharide called peptidoglycan.ell walls are found in the cells of eubacteria, archaebacteria, fungi, algae, and plants.

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.
