Chlorophyll is a complex molecule. Several modifications of chlorophyll occur among plants and other photosynthetic organisms. All photosynthetic organisms have chlorophyll a. Accessory pigments absorb energy that chlorophyll a does not absorb. Accessory pigments include chlorophyll b (also c, d, and e in algae and protistans), xanthophylls, and carotenoids (such as beta-carotene). Chlorophyll a absorbs its energy from the violet-blue and reddish orange-red wavelengths, and little from the intermediate (green-yellow-orange) wavelengths.

Answer:

Importance of chlorophyll pigment in photosynthesis: "Chlorophyll" absorbs "light energy" from the sun and converts into chemical energy. The light energy trapped is transferred to the "reaction centre of photo systems" by the resonance energy transfer through the electron transport chain. The chemi-osmotic potential is used in various steps of photosynthesis like energy production, reduction of NADP+ to NADPH and reduction of CO2 to glucose.  

"Stomata" control the flow of "carbon dioxide, oxygen, and water" to facilitate photosynthesis. During the day, stomata open to absorb "carbon dioxide" from the atmosphere to initiate photosynthesis. Stomata release oxygen out into the atmosphere. "Excess water" is released through stomatal opening and closing during transpiration.

Roots play a role in photosynthesis by absorbing water molecules which is one of the essential elements for photosynthesis along with sunlight and carbon dioxide. Roots also absorb minerals which help to activate the rate of photosynthesis.
