O Levels Biology (5090)•5090/11/O/N/24
Question 1 from 5090/11/O/N/24

Explanation

Distinguishing plant-specific cell structures

Steps:

  • List structures common to plant and animal cells: cell membrane, cytoplasm, nucleus.
  • Identify plant-exclusive structures: cellulose cell wall for rigidity, chloroplasts for photosynthesis, large sap vacuole for storage.
  • Evaluate options for lists containing only or primarily plant-exclusive features without animal-shared ones dominating.
  • Select B as it correctly emphasizes the cellulose wall as unique while noting shared components.

Why B is correct:

  • Plant cells possess a cellulose wall providing structural support and protection, absent in animal cells, per standard cell biology classification.

Why the others are wrong:

  • A: Includes cell membrane (present in animal cells) and lists "cellulose" as material, not structure.
  • C: Redundant phrasing ("cellulose cell wall") misstates the key unique structure compared to B.
  • D: Includes cytoplasm and nucleus, both present in animal cells.

Final answer: B
