krish creations   1.)  Difference between Prokaryotic cell and Eukaryotic cell. Prokaryotic cells are primitive cells mainly found in the unicellular organisms, and they do not nucleus, instead they contain a fragment of DNA, and the organelles are not bounded by the membranes, where as the eukaryotic cells are found in all types of multicellular organisms such as plant and animal cells and they contains nucleus and membrane bound organelles. Prokaryotic cells Eukaryotic cells This cells are always unicellular Eukaryotic cells are present as either unicellular or multicellular. The size of cell is generally range from 0.2 micrometers to 2.0 micrometers in diameter Eukaryotic cells range from 10 to 100 micrometers in diameter. In prokaryotic cells, the cell wall is present and it is very complex in nature. Eukaryotic cells have cell walls very rarely, if present they have simple chemical nature. In this cells true nucleus absent, instead nucleotide is present True nucleus is present. DN
