Answer 2

Each pigment absorbs a specific range of wavelengths. Chlorophyll a, the primary pigment used in photosynthesis, absorbs blue and red light. Chlorophyll b absorbs light in the blue-green and orange-red portions of the spectrum. Carotenoids absorb light in the blue and blue-green regions.

The first step in the conversion of light to chemical energy is the absorption of light by a pigment system. In all photosynthetic cells, except photosynthetic bacteria, the pigment system includes chlorophyll a. In vascular plants, bryophytes, green algae, and euglenoid algae, chlorophyll b is also found and functions as an accessory pigment. Chlorophyll B itself cannot transfer light energy into chemical energy, but it can transfer the light energy over to Chlorophyll A so that it can perform the transfer from light energy to chemical energy.

Certain carotenoids are also accessory pigments involved in the capture of light energy in photosynthesis. Carotenoids are red, orange, or yellow fat-soluble pigments found in all chloroplasts and also, in association with chlorophyll a, in the prokaryotic blue-green algae. Carotenoids are not found free in the cytoplasm, but like the chlorophylls are bound to proteins within the plastids. There are two classes of carotenoids: those that do not contain oxygen are called carotenes, and those that do contain oxygen are called xanthophylls.

In green leaves, the color of the carotenoids is masked by the much more abundant chlorophylls; in some tissues, such as those of a ripe tomato or the petals of an orange flower, the carotenoids predominate. During autumn, chlorophyll begins to break down as the leaf begins to senesce, allowing the carotenes and xanthophylls to display the brilliant red and orange colors we associate with fall.
