Prokaryotes - answerunicellular microbes that lack a true nucleus.
Example:
bacteria and archaea
Bacteria: - answerThese are single-celled prokaryotes whose cell walls are composed
of peptidoglycan (though some bacteria lack cell walls). They reproduce asexually. Most
are beneficial, but some are pathogens that cause disease
Archaea: - answerArchaea are prokaryotes whose cell walls lack peptidoglycan and
instead are composed of other polymers. They reproduce asexually. None are known to
cause disease.
Eukaryotes - answerAre organisms whose cells contain a nucleus composed of genetic
material surrounded by a distinct membrane.
Examples:
Fungi, Protozoa, Algae, Parasitic Worms, Acellular Infectious Agents - Viruses, vireos,
and prions
Fungi: - answerFungi are relatively large microscopic eukaryotes and include
multicellular molds and single-celled yeasts. These organisms obtain their food from
other organisms and have cell walls made of a polymer called chitin.
Protozoa: - answerProtozoa are single-celled eukaryotes that are similar to animals in
their nutritional needs and cellular structure. Most are capable of locomotion, and some
are pathogens that cause disease
Algae: - answerAlgae are plantlike eukaryotes that are photosynthetic; that is, they
make their own food from carbon dioxide and water, using energy from sunlight. The
algae include multicellular and unicellular organisms.
Parasitic Worms:
aka Helminths - answerParasitic worms are invertebrate worm like animals that cause
several infectious diseases. They range in size from microscopic forms to adult
tapeworms several meters in length.
Acellular infectious agents- Viruses, viroids and prions - answerare so small that they
were hidden from microbiologists until the invention of the electron microscope in 1932.
Viruses are acellular obligatory parasites and are not considered eukaryotes or
prokaryotes. Microscopes are important diagnostic tools for observing microbes and
acellular structures.
Viruses belong to the ______ category of microorganisms.
