>>12219203eukaryotic life is the typical cellular life, which generally consists of a mutually beneficial grouping of 2-3 different organisms (nucleus, mitochondria, and chloroplast) living together within a highly complex cell structure. the primary organism of eukaryotic life is the nucleus, which is what comprises the majority of the cell; the other organisms live inside of the nucleus cell. some eukaryotic life, primarily parasitic eukaryotes, can be non-mutualist, and exist without mitochondria or chloroplasts. this group contains all multicellular life, alongside some unicellular life such as protists.
prokaryotes are cellular life forms that do not live within the complex cellular environments found with eukaryotes. they are incredibly basic, non-mutualist organisms, consisting of a cellular coating containing free-floating genetic material. this group consists of bacteria, which are primarily parasitic, and archaea, that live in low oxygen environments. some parasitic bacteria, such as chlamydia, can only replicate within a host cell, giving them striking evolutionary similarities to viral life.
viruses are extremely basic non-cellular organisms. they consist of either RNA or DNA strands, contained within a protective protein. as they cannot self-replicate, all viruses are obligate parasites; to replicate, they must enter into the cell of a cellular organism. there are a significant number of types of virus, with different shapes to combat different cellular defenses.
