Diameter of mitochondria ranges between:
Correct answer: A. 0.5-1 μm
- A. 0.5-1 μm
- B. 0.5-1 nm
- C. 100-200 μm
- D. 100-200 nm
Explanation
The correct answer is that the diameter of mitochondria ranges between 0.5-1 μm. Mitochondria are important organelles within eukaryotic cells that generate most of the cell's supply of ATP, used as a source of chemical energy. The size of mitochondria allows them to effectively function within cells. Option A is correct because it accurately reflects the typical size range. Option B is incorrect because it suggests a size that is far too small. Options C and D are incorrect because they indicate sizes that are either much too large or not applicable to mitochondria.
