Correct answer: A. 0.5 micrometer
- A. 0.5 micrometer
- B. 1.5 micrometer
- C. 2 micrometer
- D. 1 micrometer
Explanation
Correct option is A. Peroxisomes are 0.1 -- 0.5μm in diameter and are bound by single membranes that enclose dense matrices primarily containing metabolic enzymes (and substrates and cofactors), which can sometimes form structured and electron dense crystalloid cores.
