To begin, here is the etymology of cytology: Cytology is derived form the Greek word, "cyto" meaning cell and "ology", meaning the study of.  So, here is a blog on the study of cells... There are two distinct cells present in our current world: eukaryote and prokaryote cells.  One way to differentiate them is knowing that eukaryotes means "true nucleus". Hence, eukaryotes all have genetic material enclosed in a nucleus, unlike the prokaryotes which has a loop of DNA, found in a plasmid. Eukaryotic cells are found in fungi, animals and plants. Prokaryotes are only present in bacteria.  So here's some history (its the endosymbiont hypothesis-I'll give you an overview )  There is a theory that the eukaryote cells have evolved from prokaryotes.  Here is the evidence that eukaryotic cells have arisen evolved from prokaryotes: Eukaryotes share similar features to prokaryotes: like they are the same size of prokaryotic cells, and can divide by binary fiss
