Diatoms stay afloat due to___________?
Correct answer: B. Stored lpids
- A. Flagella
- B. Stored lpids
- C. Pseudopodia
- D. All of these
Explanation
Diatoms remain suspended more easily because they store lipids, which are less dense than water and reduce their sinking rate. Students may choose flagella or pseudopodia because these structures can aid movement in other organisms, but they are not the usual mechanism responsible for diatom flotation.
