Empty diatom cells are called___________?
Correct answer: C. Frustule
- A. Raphe
- B. Valves
- C. Frustule
- D. Girdles
Explanation
A diatom’s rigid silica cell wall is called a frustule, and after the cell contents disappear, the empty frustule remains. The likely mistake is choosing valves, which are only the two overlapping halves that make up the frustule.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
