The prokaryotes are lower organisms that are unicellular whereas the eukaryotes can be unicellular (amoeba) or can be multicellular (higher organisms like plants, animals, fungi etc). Aside from the nucleus, prokaryotic cells contain all structures that can be found in eukaryotic cells. According to the morphological point of view, prokaryotic cells are the most primitive cells. A prokaryotic ribosome is 70S (50S+30S) while eukaryotic ribosome is 80S (60S+40S). While eukaryotic cells have a modernized cell structure containing different components in it, their size varies from 2 . Prokaryotes The word "prokaryotes" also spelled "procaryotes" is coined from two Greek words pro, before, and karyon, nut or kernel. Multiple proteins act together to fold and condense prokaryotic DNA. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. Prokaryotic and eukaryotic cells are the only kinds of cells that exist on Earth. They lack mitosis and meiosis and have a simpler genetic organization. A typical prokaryotic cell is of a size ranging from 0.1 m i c r o n s (mycoplasma bacteria) to 5.0 m i c r o n s.. 1 m i c r o n or micrometer, μ m, is one-thousandth of a millimeter or one-millionth of a meter.. prokaryotic and Eukaryotic.Prokaryotic organism are those which lacks true nucleus and membrane bound cell organelles.
