In land plants, the light-harvesting antennae around photosystem II contain the majority of chlorophyll b. Chlorophyll does not absorb the color green.For this reason, the leaves of many plants appear green, as most other colours of light are absorbed (and therefore, are not reflected, and cannot be seen). 4. A. Chlorophyll b absorbs a lot of energy from 460 nm wavelengths. How does chlorophyll absorb light energy and pass it on to the energy-requiring reactions of photosynthesis? b) Because the absorption spectra of the pigments are highest in the purple/blue wavelengths, we can assume that red light is not effective. What color are these? What wavelengths of light does chlorophyll b absorb best? 1 decade ago. Both Chlorophyll a and Chlorophyll b can best absorb light at the 450 nm to 650 nm spectrum. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. Animals that eat plants or other animals are called heterotrophs. c What is the frequency, in MHz, associated with each wavelength? D)a more efficient pigment. 1. Chlorophyll absorbs light of the red and blue wavelengths more. It helps in a wider scope of absorption of light for photosynthesis. It is the accessory pigment that collects energy and passes it on to chlorophyll a. The color is between indigo and blue. d. When chlorophyll b absorbs light, electrons transition energy levels.
