AP Biology B
| Question | Answer |
|---|---|
| An informal term applied to any eukaryote that is not a plant, animal, or fungus. Most protists are unicellular, though some are colonial or multicellular. | protist |
| An organism that is capable of both photosynthesis and heterotrophy. | mixotroph |
| A protist that has modified mitochondria, two equal-sized nuclei, and multiple flagella. | diplomonad |
| A protist, such as a trichomonad, with modified mitochondria. | parabasalid |
| A protist, such as a trypanosome, that has a single large mitochondrion that houses an organized mass of DNA. | kinetoplastid |
| A protist, such as Euglena or its relatives, characterized by an anterior pocket from which one or two flagella emerge. | euglenid |
| A protist with membrane-bounded sacs (alveoli) located just under the plasma membrane. | alveolates |
| A protist in a clade that includes many species that parasitize animals. Some apicomplexans cause human disease. | apicomplexan |
| A type of protist that moves by means of cilia. | ciliate |
| A unicellular photosynthetic alga with a unique glassy cell wall containing silica. | diatom |
| A biflagellated, photosynthetic protist named for its color, which results from its yellow and brown carotenoids. | golden algae |
| The study of energy transformations that occur in a collection of matter. See first law of thermodynamics; second law of thermodynamics. | thallus |
| A stemlike structure of a seaweed. | stipe |
| Referring to a condition in the life cycle of plants and certain algae in which the sporophyte and gametophyte generations differ in morphology. | heteromorphic |
| Referring to alternating generations in plants and certain algae in which the sporophytes and gametophytes look alike, although they differ in chromosome number. | isomorphic |
| A protist with flagellated cells, such as a water mold, white rust, or downy mildew, that acquires nutrition mainly as a decomposer or plant parasite. | oomycetes |
| A protist grade characterized by the presence of pseudopodia. | amoebas |
| A protist, usually marine, with a shell generally made of silica and pseudopodia that radiate from the central body. | radiolarian |
| A protist in a clade that includes many species with lobe- or tube-shaped pseudopodia. | amoebozoans |
| Member of the diverse clade Opisthokonta, organisms that descended from an ancestor with a posterior flagellum, including fungi, animals, and certain protists. | opisthokont |
