Before we get to the part about the phenomenon or types of cell division, let's take a closer look at the two basic types of organic cellular structures that exist in this world as we know it. A cell can be either prokaryotic or eukaryotic, based upon its structural makeup. Prokaryotic cells have a simple, very basic structure as they neither have cell nuclei nor are they equipped with cellular organelles enclosed within membranes. In other words, all genetic matter and other areas partaking in various cellular functions and metabolic activities exist in free states within the cellular boundaries. Eukaryotic cells, on the other hand, are the more evolved, hi-tech counterparts of prokaryotic cells. They have all things that prokaryotic cells lack - cell nuclei holding all the genetic matter of the cells inside them, separate membrane bound organelles that have exclusive and specific tasks assigned to them (such as mitochondria, Golgi apparatus, chloroplasts, etc.), etc.
As you must have guessed by now, the more complex an organism is in terms of its physical structure and physiological functions, the more it is likely to have a eukaryotic cellular structure. This fact is evidenced by the fact the simplest of all life forms such as bacteria and archaea belong to the prokaryotic domain of biological classification. Now that the particulars of the two basic cellular structures have been discussed, let's move ahead to the next segment and take a look at what the various different types of cell division are.
