microbio

microorganisms

can be unicellular or multicellular or like viruses they can be acellular

found in all three domains of life

domains of life

arachea, bacteria, eukarya

Microbes with the domains bacteria and arachea

prokaryotes

microbes with the domain eukarya

eukaryotes

do viruses fall within the three domains of life

no

pathogen

most bacteria is harmless, but ______ are harmful causing disease in humans and animals

bacteria

prokaryotic because their DNA is not in a true nucleus. it is in a peptidoglycan

photosynthetic bacteria

use energy derived from sunlight and fix carbon dioxide for growth

nonphotosynthetic bacteria

obtain energy from organic and inorganic compounds in their environment

Archaea

unicellular prokaryotic organism

-do not contain peptidoglycan; instead psuedopeptidoglycan

-found in every habitat on earth

-some can be in the human body

eukaryotic microorganisms

contains all eukaryotes (unicellular and microunicelluar) such a protists, fungi, plants and animals

-contains a nucleus

protists

grouping of eukaryotes that are not plants, animals, or fungi. some algae and others bacteria

fungi

eukaryotes, some multicellular fungi. different than mushrooms

-not photosynthetic

-walls are made out of chitin

viruses

acellular microorganism

-consists of proteins and genetic material (either DNA or RNA) that are inert outside of host

-many viruses can not cause disease but can affect all cell types

-can multiply/infect in host
