How many rings does chlorophyll a and b have​
In-s [12.5K]

Explanation:

Each has one chlorin ring- chlorin is a form of porphyrin.

Chlorophylls  are comprised of a ringed molecule, chlorin, a hydrogenated form of porphyrin which contains a magnesium ion at the center, bonded to four atoms of nitrogen.  Varying types of Chlorophyll have side chains, which affect the absorption spectrum of the molecule for instance A has a methyl group bonded to the C7 position, while B has an aldehyle (CHO) group at this location.

Embedded within the thykaloid membrane of chloroplasts, chlorophyll a and B mainly absorb orange-red and violet-blue wavelengths and convert light energy into chemical energy for the process of photosynthesis. This occurs in the light-dependent reactions of photosynthesis, within chloroplasts of plants. The range of wavelengths absorbed by a pigment is its absorption spectrum while it reflects those outside of this range. Plants appear green as this region of light is reflected by the pigments.
