Cell wall is a fairly rigid‚ protective and supportive layer surrounding the cell external to plasma membrane of plants‚ bacteria‚ archaea‚ fungi and algae. It is absent in animals and most protists. It was first observed by Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cells‚ cell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)

[pic] Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla‚ families and genera have some species that live in the sea and others that live on land‚ marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment‚ and biology is the study of the organisms
