Bacteria, Protists, Fungi, and Plants

An Amoeba

The shape of the bacteria is spherical or round.

Bacteria are prokaryotes, which means that there is not a membrane around the nucleus in a bacterium cell. These cells are smaller and microscopic.

Nitrogen-fixing bacteria converts nitrogen in the air and soil so that plants can use it.

A prokaryotic cell does not have a membrane around its nucleus. These cells are smaller and microscopic.

Cilia are bristle-like structures on some protists that help them move.

Endospores are thick- walled structures around bacteria that protect bacteria and make it difficult to treat with antibiotics or vaccines.

An antibiotic is medicine produced by one organism and kills another organism such as bacteria.

 Medicines  Nitrogen-fixing bacteria  Saprophytes  Help clean up oil spills and other pollution

 Plant-like  Animal-like  Fungus-like

Aerobes- organisms that use oxygen for respiration Anaerobes- organisms that do not use oxygen for respiration

An organism that uses dead material as a food and energy source. Bacteria is a saprophyte.

Saprophytes control environmental pollution by breaking down dead and decaying material.

Shared characteristics – plant-like, animal-like, and fungus-like

Spirilli-spirillu m

A pathogen is an organism that causes a disease.

Cocci - coccus

Aerobes

A vaccine is a solution made from dead or damaged bacteria that is used to prevent bacterial diseases.

Binary fission

Bacilli - bacillum

Flagellum is a long, whip- like structure on some protists that help them move.

Toxins are poisons produced by pathogens.

anaerobes

Nitrogen-fixing bacteria

Thick-walled structures around bacteria

saprophytes

Bacteria are one-celled organisms without membrane-bound cells(nucleus).

Fission is the way all bacteria reproduce.

Archaebacteria are found in extreme environments such as Great Salt Lake, Dead Sea, ocean vents, geysers, and swamps.

Cheese, yogurt, sauerkraut

Vaccines and antibiotics

Eukaryotic Heterotrophic Multicellular Decomposer Can be parasitic

Trees Angiosperms- flowering plants Ferns Horsetails and Club Moss

Can make their own food – autotrophic Have a cell wall Multicellular Eukaryotic cell

Fungus

To identify an unknown organism

There are two choices.

The two-part naming system used to name organisms.

The genus is the first part of the name; the species is the second part of the name. The genus is always capitalized.

Linnaeus

Bacteria – Eubacteria and Archaebacteria

A eukaryotic cell has a membrane around the nucleus and other organelles.
