Answers

1. B) Mitochondria – They turn food into energy (ATP).
2. B) Nucleus – It stores genetic material and directs cell activities.
3. B) Cytoplasm – It is the jelly-like substance where many chemical reactions happen.
4. A) Ribosomes – They are responsible for protein synthesis.
5. C) Cell wall – It provides rigid outer support made of cellulose in plant cells.

6. C) Ribosomes – They synthesize proteins and are found in both cell types, while other organelles are not found in prokaryotes.

7. C) Muscle cell requires more ATP – Muscle cells actively contract and need more mitochondria to produce energy.

8. D) Can perform photosynthesis – The presence of chloroplasts means the cell can capture sunlight to make food.

9. B) Chloroplast – This is the specific plant organelle where light-absorbing chlorophyll a is located.

10. Bacterial cell (Prokaryote) – It lacks a nucleus and membrane-bound organelles, so its DNA floats freely in the cytoplasm.
