Question 24

Animal cells do not use chloroplasts to gain energy.

Animal cells rely on mitochondria for energy production, not chloroplasts, which are found in plant cells. Thus, the statement about animal cells using chloroplasts is false.

A) Animal cells use lysosomes to break down old cells

This statement is true. Lysosomes are membrane-bound organelles that contain enzymes responsible for digesting cellular waste and breaking down old or damaged cells in animal cells.

B) Animal cells use chloroplasts to gain energy

This statement is false. Chloroplasts are responsible for photosynthesis and are found only in plant cells and some algae. Animal cells do not possess chloroplasts; they generate energy through mitochondria.

C) Plant cells have a cell wall to maintain structure

This statement is true. Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection, distinguishing them from animal cells.

D) All of the above are true

This statement is false. Since option B is incorrect, stating that all options are true is also false. Therefore, this option cannot be correct.

Conclusion

Option B is definitively the correct choice because it inaccurately states that animal cells use chloroplasts for energy, which is not true as animal cells utilize mitochondria. Meanwhile, options A and C are accurate descriptions of cellular functions, and option D fails because it includes the false statement in B. Thus, B clearly stands out as the incorrect assertion about cell structures.
