Document Summary
Taxonomy: variety of ions and organic molecules necessary of life (these last ones require energy to be; which came from some sort of electrical discharge conversion, they form under simple conditions) Organisms may also reproduce by type of reproduction: sexual: haploid cells (gametes) fuse to form a diploid cell called a zygote, asexual: there is no fusion of haploid cells (gametes) Domain bacteriae: cyanobacteria: anabaena stay gathered in the firm of filaments. They are unicellular but they have units called heterocyst that can make photosynthesis; they are photoautotrophs: prokaryotes, bacterial cells can be shaped in spherical form, like the streptococcus bacteria; in a long thin form. There are also spiral bacteria and smaller cells too: they reproduce by simple binary fissions (asexual reproduction) and conjugation through connection of the plasma membrane. Domain archaea: these are also prokaryotes like bacteria, archaea actually share many biochemical traits with the eukarya group, not the bacteria.
