6. what is the main function of the green pigments (chlorophyll a & b)?

Answer and Explanation:

Chlorophyll a is the most used photosynthetic pigment and absorbs blue, red and violet wavelengths in the visible spectrum. It participates mainly in oxygenic photosynthesis in which oxygen is the main byproduct of the process. Chlorophyll b primarily absorbs blue light and is used to complement the absorption spectrum of chlorophyll a by extending the range of light wavelengths a photosynthetic organism is able to absorb.

Both of these chlorophyll molecules capture light energy and transfer it to the reaction center of the cell. Henceforth, electrons are passed from this absorbed light energy to water molecules resulting in the formation of hydrogen ions and oxygen atoms.

you are the source of the heat energy. you can minimize the heat energy by selecting the appropriate clothes to wear.
