The three-domain system is a biological classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to

ζῷα zoa "animals"; singular protozoon) are microorganisms classified as unicellular eukaryotes.[1] While there is no exact definition of the term "protozoan"‚ most scientists use the word to refer to a unicellular heterotrophic protist‚ such as an amoeba or a cilipoopate. The term algae is used for microorganisms that photosynthesize. However‚ the distinction between protozoa and algae is often vague. For example‚ the alga Dinobryon has chloroplasts for photosynthesis‚ but it can also feed on organic

death among your residents would you do it? In Louisiana there are six parishes surrounding Orleans parish which is New Orleans that have problems or worries about amoeba’s being present in their water supply. It seems in order that I explain what an amoeba is so you know what all the fuss is about. Also‚ I am going to discuss my opinion about what and why the parishes take certain precautions. To keep all residents safe these parishes should take all necessary precautions to prevent any sickness or

Most sarcodines are free living; others are parasitic. One of these parasites is the causative organism of amebic dysentery. With the exception of chloroplasts‚ sarcodines are identical to the ameboid members of the phylum Chrysophyta. Sarcodines may reproduce asexually by cell division‚ often without breakdown of the nuclear
