Which one is a part of the mitochondrion?
Think it through first, then pick an option.
- a Oxysome
- b Granum
- c Cisternae
- d Centriole
Answer and explanation
Correct answer: a Oxysome
The oxysome is the stalked round body on the cristae, so it is a part of the mitochondrion.
Why the other options are wrong
- b Granum: The granum is a part of the chloroplast, not of the mitochondrion.
- c Cisternae: Cisternae are the flat sacs of the Golgi body, not parts of the mitochondrion.
- d Centriole: The centriole is a part of the centrosome, not of the mitochondrion.
