Of the following which one has glassy shells________________?
Correct answer: A. Radiolarians
- A. Radiolarians
- B. Forams
- C. Both of these
- D. None of these
Explanation
Radiolarians have delicate, glass-like skeletons made mainly of silica, giving them a transparent or glassy appearance. Foraminiferans usually possess shells made of calcium carbonate, so their shells are not described as glassy. Students may choose both by confusing the mineral shells of these two protist groups.
