Chlorophyll consists of:
Correct answer: D. It has a head of four pyrrole rings and a phytol tail
- A. A head of phytol and a tail of four pyrrole rings
- B. A head of linked carbons and a tail of four pyrrole rings
- C. A head of four pyrrole rings and a tail of linked nitrogen
- D. It has a head of four pyrrole rings and a phytol tail
Explanation
The chlorophyll molecule consists of two main parts: a hydrophilic head and a hydrophobic tail. The head, which is responsible for absorbing light, is a porphyrin ring made up of four pyrrole rings. This structure is crucial for the molecule's function in photosynthesis. The tail, which is hydrophobic and helps anchor the chlorophyll within the thylakoid membrane of the chloroplast, is a phytol chain. The incorrect options either misidentify the components or their arrangement, failing to describe the classic chlorophyll structure.
