Which one controls all the metabolic work of the cell?
Think it through first, then pick an option.
- a Plastid
- b Nucleus
- c Mitochondrion
- d Golgi body
Answer and explanation
Correct answer: b Nucleus
The nucleus controls all the reactions of the cell, including metabolic work.
Why the other options are wrong
- a Plastid: The plastid makes food; metabolism is controlled by the nucleus.
- c Mitochondrion: The mitochondrion supplies energy; it is not the controller of metabolism.
- d Golgi body: The Golgi body is linked with secretion; metabolism is controlled by the nucleus.
