Write an essay on biological membranes explaining how membranes are an important concept/phenomenon in biology and how it is related in our everyday life.

 I need a two page essay on biological membranes that includes at least 3 sources and MUST be at least 550 words. Aside from introducing membranes (with biological terms and concepts), the essay must include how membranes are an important concept/phenomenon in biology, how it is related in our everyday life, and why people would find it interesting. Must be original writing with the sources cited within the essay itself.
