    can diffuse across cell membranes while some substances   must be transported across the membrane by proteins. The membrane is in control of   what enters and leaves the cell. However‚ certain conditions may damage the cell   membrane’s structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment   called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s   membrane‚ acts with the cell membrane of the cell to prevent the betacyanin

    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 cellscell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)

    The prokaryotic cell precedes any forms of Bacteria‚ Archaea‚ and eventually Eukaryotes by approximately two billion years. This cell was the original life form on the planet and represents the smallest and least complex of all organisms. Through the process of mutation and adaptation they were able to survive to evolve into our modern day Bacteria‚ Archaea‚ Fungi and Protists. These post organisms have benefited from their early ancestor‚ by way of Endosymbiosis. Intricate protest and fungi are
