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.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
