INTRODUCTIONAll living organism are made up of cells. It is known as biological unit. It is the smallestunit of life and can easily duplicate or replicate itself independently (Prescott, 2012). So cellbiology is nothing but the study of cells. Cell contains cytoplasm that is encapsulated within amembrane. This membrane consist of large amount of biomolecules like protein and nucleicacid. There are two types of organism namely unicellular and multicellular. Unicellularorganisms contains only one cell but multicellular contains large number of cells. The presentreport is based on the introduction to cell biology. In this project, similarities and differencesbetween prokaryotic and eukaryotic cells are described . Additionally, the model of fluid mosaicis also explained.PART 11 Differences and similarities between prokaryotic and eukaryotic cellsThe differences between prokaryotic and eukaryotic cells are following:Prokaryotic cellsEukaryotic cellsThey are very tiny or small in size.They are fairly larger than size of prokaryoticcells.Nuclear region is not covered by any nuclearmembrane.Here nuclear membrane is present outside thenuclear region.Here nucleolus is not present.Nucleolus is present here.There is absence of membrane bound cellorganelles also.Here membrane bound cell organelles arepresent.Cell division occurred by the process of fissionor budding.While here cell division occurs by mitosis ormeiosis.This consist of circular DNA.Where as DNA is present in linear way.Only asexual production is happened here.But here production can be done via asexualand sexual both.It has no cytoskeleton.While it has always a cytoskeleton.Several prokaryote has single chromosome.On the other hand Eukaryotes consists ofmultiple linear chromosomes.Extra chromosomal plasmid are found in this.But it is absent in this case.
