Chlorophyll is a/an _____ molecule?
Correct answer: D. Organic
- A. Inorganic
- B. Cationic
- C. Anionic
- D. Organic
Explanation
Chlorophyll is an organic molecule because it is a carbon-based pigment with a complex ring structure and a magnesium ion at its centre. The likely mistake is choosing inorganic because chlorophyll contains magnesium, but the presence of one metal ion does not make the entire carbon-based molecule inorganic.
