Domain Bacteria Is A What

They are single celled organisms.

Domain bacteria is a what. The largest number of bacteria are saprobic meaning that they feed on dead or decaying organic matter. Archaea and bacteria are prokaryotic organisms that lack membrane bound organelles and a nucleus. And eubacteria or bacteria which includes all other bacteria.

Microorganism transfer genes to other microorganisms through horizontal gene transfer the transfer of dna to an organism that is not its offspring. Extreme cold surrounded by a cell wall of peptidoglycan which protects the cell from injury and determines its shape. Gram positive bacteria stain purple when treated with the counterstain because of high levels of peptidoglycan.

Domain archaea kingdom archaebacteria. Most bacterial species are heterotrophic. Archaea bacteria and eukarya.

Eucarya which are plants animals fungi chromist algae and plankton and protists. Prokaryotic organisms belong either to the domain archaea or the domain bacteria. That is they acquire their food from organic matter.

Small lack an enclosed nucleus and few other organelles. There are more bacteria in a person s mouth than there are people in the world. However some are pathogenic organisms that result in mild to severe diseases.

Domain bacteria includes the prokaryotes people encounter on an everyday basis. What is the importance of knowing if an organism is gram positive or gram negative. The bacterial domain includes all bacteria eubacteria and cyanobacteria blue green algae which are the most present forms of this domain.
