Protists Flashcards
Protozoan
animal-like protist that can move to obtain food.
Pseudopods
“false feet”. Used by an amoeba for moving and obtaining food. Always changing shape.
Contractile vacuole
a cell structure that collects extra water and expels it from the cell.
Symbiosis
the interaction between two species of organisms
Mutualism
When both species benefit from living together.
Spore
a tiny reproductive cell that can develop into a new organism
Algae
plant-like protists
Pigments
chemicals that produce color
Algal Bloom
A rapid growth of a population of algae
Red Tides
saltwater algal blooms
Eutrophication
an increase in algae growth as a result of an increase in nutrients.
Hyphae
branching, thread-like tubes that make up the bodies of fungi
Fruiting Bodies
the structures in fungi that contain the spores for reproduction.
Budding
a form of asexual reproduction used by yeast. No spores are produced. Instead, a small yeast cell breaks away from a larger parent cell.
Lichen
consists of a fungus and either algae or autotrophic bacteria living together in a mutualistic relationship. The algae (or bacteria) makes food for both and the fungus provides water for both. Often seen living on rocks.
