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.

Middle lamella - outer cell wall layer that contains polysaccharides called pectins. Pectins aid in cell adhesion by helping the cell walls of adjacent cells to bind to one another.â. Primary cell wall - layer formed between the middle lamella and plasma membrane in growing plant cells.
