Bacteria Basics
This is the shape category used to describe spherical bacteria.
Coccus
Unlike bacteria, all protists are this type of organism.
Eukaryotes
These plant-like protists are important producers in aquatic food chains.
Algae
Most fungi perform this role in their environments by breaking down dead organic material.
These are the sexual spores produced by ascomycetes.
Ascospores
Bacteria reproduce through this process, in which one cell divides into two identical cells.
Binary fission
This is NOT a protozoan group: sporozoans, ciliates, diatoms, or amoebas.
Diatoms
These organisms may cause harmful red tides.
Dinoflagellates
This group includes mushrooms, puffballs, and bracket fungi.
Basidiomycota
These are produced when zygomycetes reproduce sexually.
Zygospores
This is the process in which bacteria convert gaseous nitrogen into forms plants can use.
Nitrogen fixation
These single-celled organisms use flagella and can have both plant-like and animal-like characteristics.
Euglenoids
This group of algae can survive in the deepest water because its pigments absorb blue light.
This is the basic structural unit of multicellular fungi.
Hypha (hyphae)
These specialized hyphae allow parasitic fungi to penetrate and absorb nutrients from host cells.
Haustoria
Bacteria arranged in long chains of round cells are identified by this name.
Streptococcus
This is NOT a characteristic of euglenoids: they use flagella, live in moist environments, have plant-like and animal-like characteristics, or are multicellular.
Multicellular
This group of algae is known for its ability to move using flagella and can also obtain food heterotrophically.
Euglenoids
This complex carbohydrate makes up the cell walls of most fungi.
Chitin
In a mutualistic relationship with a plant, fungi can help their host by providing this important resource.
This process allows bacteria to transfer DNA from one cell to another through a pilus.
Conjugation
This group of protists includes organisms that move using cilia.
Ciliates
This type of algae is commonly found in aquatic environments and has silica cell walls. Many layers of fossilized remains of these are found at the bottom of the ocean.
Diatoms
This group of fungi includes the organism from which penicillin was originally discovered.
Ascomycota
This type of symbiotic relationship involves fungi and plant roots, allowing both organisms to benefit.
