Mitosis and binary fission

• Mitosis is the division of the nucleus in a diploid cell (that is, a cell containing 2 sets of chromosomes). It occurs in eukaryotic cells. Generally, it is followed by cytokinesis, which is the splitting of the cell membrane, thus completing the process of 'duplicating' or dividing of the cell. 
• Fast and highly complex
• Eukaryotes (animal cells)
• 
• Binary Fission is the form of asexual reproduction in single-celled organisms. It is the division of one cell into two cells of the same size. This happens in prokaryotic cells, as opposed to eukaryotic cells. Binary fission produces two separate cells, as opposed to multiple fission which produces more than two cells.
• Simple process
• Prokaryotes (multiple fission occurs in many protists, e.g. sporozoans and algae.)
