Animal-Like Protists
Question | Answer |
---|---|
Mastigophora | group of animal-like protists that are commonly known as flagellates and move by their flagella, an example is trypanosoma |
Sarcodina | group of animal-like protists that are commonly known as sarcodines, they move by pseudopods (false feet) and an example is the amoeba |
Ciliophora | group of animal-like protists that are commonly known as ciliates, move by using their cilia, and an example is a paramecium |
Sporozoa | group of animal-like protists that are commonly known as sporozoans, they do not move, an example is a plasmodium |
Flagellates | type of protists that are characterized by their specialized flagella |
Autotrophs | organisms that use nonliving energy sources, usually chemical or light, to create and store their own energy, mainly through photosynthesis |
Heterotrophs | organisms that depend upon organic compounds produced by autotrophic organisms for their source of energy, we are examples of this group |
Pseudopods | extensions from the cytoplasm of some protozoa, which are used for feeding and locomotion |
Sarcodine | type of protist that is characterized by its lack of rigidity, allowing it to change shape freely |
Phagocytosis | process of feeding in which the cell’s protoplasm surrounds a food source and encloses it in a food vacuole where it is digested |
Axopods | needle-like pseudopodium present in some types of sarcodines |
Ciliates | type of protist characterized by numerous cilia and trichocysts |
Cilia | hair-like structures used by ciliates for locomotion and feeding |
Trichocysts | specialized organelle that ciliates use to anchor themselves and to capture and/ or immobilize food |
Conjugation | reproductive process that takes place in many microscopic organisms, mainly protists and fungi |
Sporozoa | parasitic protozoa that cause numerous diseases in animals, including humans |
