Which of the following is a difference between chlorophyll a and chlorophyll b? chlorophyll a contains a mg in its ring structure, whereas chlorophyll b contains iron. chlorophyll a is a pigment, and chlorophyll b is the enzyme that transfers excited electrons from chlorophyll a to electron carriers of the thylakoid membrane. chlorophyll a and b absorb light energy at slightly different wavelengths. chlorophyll a absorbs yellow light, and chlorophyll b absorbs green.

The correct answer is C) Chlorophyll a and b absorb light energy at slightly different wavelengths

Explanation:

Chlorophyll is the most common and important pigment among plants. Type a has its absorption peak closer to the 400 nm, meanwhile, the b type has its absorption peak closer to 500 nm. This means that the wavelengths are slightly different, and this changes a bit their functions.
