why is a protozoan considered animal - like?\nit is a heterotroph.\nit is multicellular.\nit has a flagellum.\nit has a cell wall.
Answer
Brief Explanations:
- Heterotroph: Animals are heterotrophs (obtain food from outside source). Protozoans are also heterotrophs.
- Multicellular: Most protozoans are unicellular. Animals are multicellular, so this is incorrect.
- Flagellum: Some protozoans have flagella (e.g., Euglena), but not all animals have structures similar to flagella. Also, having a flagellum is not the key characteristic to classify as animal - like.
- Cell wall: Animal cells do not have a cell wall. Many protozoans do not have a cell wall (while some plant - like protists do), but the absence of a cell wall is not the main reason for being animal - like. The main reason is the heterotrophic mode of nutrition.
Answer:
It is a heterotroph.
