Prokaryotes vs. Eukaryotes

    Prokaryotes are cells that have no membrane-bound nucleus nor any membrane-bound organelles. Prokaryotes are mainly bacteria or archaebacteria.These type of cells lack a nucleus so they have a very similar region called a nucleoid. Like the nucleus, the nucleiod region is where DNA is stored. Prokaryote cells are all unicellular and they all divide by binary fission. Binary Fission is when a cell starts making two complete sets of DNA. When this happens, the cell starts to enlarge. The two complete sets of DNA then move to opposite ends of the cell. When the cell becomes large enough, it then divides the cell in two. 
    On the other hand there are eukaryotic cells. Eukaryotes are cells that have a membrane-bound nucleus and have several membrane-bound organelles. All of these organelles perform specific funtions for the cell; in return these cells help keep us healthy. These types of cells are either unicellualar or multicellualar which consist of animals, plants, fungi, or protists. All of these cells are usually larger than prokaryotic cells and they all divide by meiosis or mitosis. Meiosis is the process of cell division in which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells. Mitosis occurs only in eukaryotic cells. This cell division is the process that forms two nuclei, each of which has the same number of chromosomes.
    Prokarotes and Eukaryotes are very different from each other, but also have similarities.
