It literally means âby way of e-mailâ which probably doesnât help either. In the âold days,â paper letters could be sent via courier, via air mail. It simply means e-mail was involved.
Taxonomy. Bacteria are members of the prokaryote group. In contrast to eukaryote cells, bacteria lack a cell nucleus and customarily have no organelles. The bacteria domain can be grouped into two major categories: (a) Eubacteria and (b) Cyanobacteria.here are approximately 50 million bacterial organisms in a single gram of typical surface soil. The worldwide bacterial biomass exceeds that of all plants and animals on Earth. However, the majority of bacteria have not yet been characterised.
Bacteria are single-celled organisms that lack a nucleus, mitochondria, chloroplasts, golgibodies and ER. Organisms are important to our existence as humans and all other living things evolved from them. Organisms can be classified into two categories: eukaryote and prokaryotes. Prokaryotes microorganisms can be further classified into three domains: eukarya, bacteria and archaea.
