Bacteria, Protists, Fungi, and Plants
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.
Help clean up oil spills and other pollution
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
A pathogen is an organism that causes a disease.
Cocci - coccus
A vaccine is a solution made from dead or damaged bacteria that is used to prevent bacterial diseases.
Bacilli - bacillum
Flagellum is a long, whip-like structure on some protists that help them move.
Toxins are poisons produced by pathogens.
Thick-walled structures around bacteria
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
Can be parasitic
Angiosperms- flowering plants
Horsetails and Club Moss
Can make their own food – autotrophic
Have a cell wall
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.
Bacteria – Eubacteria and Archaebacteria
A eukaryotic cell has a membrane around the nucleus and other organelles.
