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.

Structures Found Only in Plant (and Some Algae and Fungal) Cells Now, we move on to the fun stuff that you only wish you had in your cells. It's okay to be jealous. Cell Wall Like the cell walls in bacteria, fungi, algae, and some archaea, plant cell walls are found just outside the plasma membrane and provide the cells structure and protection. The Cell Wall: Not Yours. The cell wall prevents plant cells from bursting (lysing) when too much water moves into the cell across the membrane. As water pushes against the cell wall from the inside, plant cells become large and firm because pressure, known as turgor pressure, builds up against the inside of the cell wall.
