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.

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.
