algal bloom
Large increase in population size of single-celled photosynthetic protist as a result of nutrient enrichment of body of water.
alternation of generations
Alternation of haploid (gamete-producing) and diploid (spore-producing) multicelled phases in the life cycle of an organism.
alveolate
A type of single-celled eukaryote with many tiny, membrane-bound sacs just beneath the plasma membrane; e.g., ciliate, apicomplexan, or dinoflagellate.
amoeba
A solitary amoebozoan protist that moves about on pseudopods. All are predatory or parasitic.
apicomplexan
A parasitic alveolate protist that penetrates the host cell using a unique microtubular structure; e.g., malaria-causing Plasmodium species. Sexual Stages include: gamonts, gamogony, fertilization, and sporogony.
binary fission
Asexual reproductive mode of some protists. (reproduction of bacterial cells whereby a single cell splits into two identical daughter cells).
brown alga
A stramenopile; a multicelled marine autotroph with an abundance of the pigment fucoxanthin; e.g., kelps.
charophyte algae
Green algal lineage most closely related to land plants.
chlorophyte
Member of the most diverse lineage of green algae.
ciliate
A heterotrophic alveolate protist with cilia at its surface; also known as a ciliated protozoan; e.g., Paramecium.
contractile vacuole
In freshwater protists, an organelle that collects and then expels any excess water that moves into the cell by osmosis.

In freshwater protists, an organelle that collects and then expels any excess water that moves into the cell by osmosis.
cyst
Of many microbes, a hardy resting stage. (bladder, sac)
diatom
A photosynthetic stramenopile (protist) that lives as a single cell inside a two-part silica shell. (an important group of algae living in fresh and sea water).
dinoflagellate
Alveolate protist typically having two flagella; deposits cellulose in alveoli. Heterotrophs and photoautotrophs; some cause red tides.
euglenoid
A flagellated protist with many mitochondria. Majority are heterotrophs, others photoautotrophs.
flagellated protozoan
One of the single-celled heterotrophic protists having one or more flagella; e.g., a diplomonad.
foraminiferan
Heterotrophic single-celled protist that extends its pseudopods through a perforated calcium carbonate or silica shell. Most live on the ocean floor.
oomycote/water mold
A stramenopile protist; most are decomposers or opportunistic parasites, of aquatic habitats; others are plant pathogens.
pellicle
A thin, flexible, protein-rich body covering of some single-celled eukaryotes such as euglenoids.
plankton
Mostly microscopic autotrophs and heterotrophs of aquatic habitats.
protists
Informal name for eukaryotes that are not plants, fungi, or animals.
radiolarian
Single-celled predatory protist with pseudopods that project through its perforated silica shell. Most drift in open upper ocean waters.
red alga
An aquatic, usually multicelled autotrophic protist with an abundance of phycobilins.
slime mold
An amoebozoan; amoeba-like cells that cluster into a mass, differentiate, and form reproductive structures.
stramenopile
A single-celled or multi-celled protist of a group united by DNA studies; some have cells with filaments on one of two flagella; e.g., a diatom, brown alga, or water mold.
trypanosome
Member of the largest subgroup of kinetoplastid protozoans; all are parasites.
