Protists with two nuclei
Correct answer: C. Ciliates
- A. Actinopods
- B. Zooflagellates
- C. Ciliates
- D. Apicomplexans
Explanation
Ciliates are a group of protists distinguished by having two types of nuclei: a macronucleus and one or more micronuclei. The macronucleus controls non-reproductive cell functions, while the micronuclei are involved in reproductive processes. This distinct feature sets them apart from other protists. Actinopods, zooflagellates, and apicomplexans do not typically have two nuclei; instead, they are characterized by other features such as their movement mechanisms or parasitic nature.

About Kingdom Protista
Kingdom Protista contains mainly unicellular eukaryotes, although some forms are colonial or multicellular, with varied nutritional and reproductive methods. Questions examine protozoans, algae and examples such as Amoeba, Paramecium and Euglena, while distinguishing protists from prokaryotes, fungi and true plants.
