Bacteria, however, lack a nucleus, and their DNA floats freely within the cell. These microscopic cells don't have organelles and possess different methods to reproduce and swap genetic material. Bacteria are classified as prokaryotic cells. Basic categories aside, scientists also place bacteria in ...

Now Come the Animals Although plants account for more than 90 percent of the earth’s two trillion tons of biomass, they represent only some 20 percent of earth’s classified and named organisms. In contrast, while the animals make up only a small fraction of the biomass, they represent mor...
Pathogenic bacteria are commonly classified as intracellular or extracellular pathogens. Intracellular bacterial pathogens can replicate within host cells, including macrophages, which ingest and kill microorganisms in a process called phagocytosis. By contrast, extracellular pathogens such asPseudomonas aeruginosa...
