Centric discoid form of diatoms is__________?
Correct answer: B. Coscinodiscus
- A. Diplaneis
- B. Coscinodiscus
- C. Camphyloneiscus
- D. Stephanodis
Explanation
Coscinodiscus is a well-known centric diatom with a circular or discoid frustule. Diploneis and related names refer to other diatom forms, so selecting them confuses different genera rather than recognizing the classic discoid example.
