The primary role of chlorophyll is to absorb light energy for use in a process called photosynthesis the process by which plants, algae and some bacteria convert light energy from the sun into chemical energy. The energy absorbed from light is transferred to two kinds of energy-storing molecules. What is the role of photosynthetic pigments in the process of photosynthesis? Green plants have the ability to make their own food. They are used to replace the "electron hole" left in photosystem II when electrons are passed down the electron transport chain to photosystem I. a.) 10 What are the parts and functions of the chloroplast? The presence of chlorophyll is necessary for photosynthesis because it absorbs light energy and transports it to two different types of storage molecules. For a majority of organisms capable of photosynthesis (plants, cyanobacteria, algae) chlorophyll a is the primary pigment of photosynthesis. The primary pigment of photosynthesis is chlorophyll A. Chlorophyll B is an accessory pigment because it is not necessary for photosynthesis to occur. E. The level of liquid in the volumeter would fall since atmospheric pressure is greater than the pressure within the test tube. Light is absorbed into two types of molecules that convert it into energy. Other plant cell ATP needs are satisfied by cellular respiration (in mitochondria). Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. C. Colorless Almost all organic material on Earth is produced by cells that convert solar energy into macromolecules containing energy. 52. The two parts of the biochemical pathway of photosynthesis are the energy-fixing reaction and the carbon-fixing reaction. Photosynthesis occurs in two stages. Which is the best procedure for preparing this solution? Energy from the electrons is used by the proteins in the chain to pump hydrogen ions from the stroma into the thylakoid space. Flowers. The products of photosynthesis (glucose and oxygen) are the reactants of respiration. C. Xanthophyll Light Dependent Reaction - Occurs within the thylakoid membranes Light Independent Reaction - Occur in the stroma. False.

Plants that use photosynthesis to make their own food are called autotrophs. Different pigments respond to different wavelengths of visible light. Photosynthesis comprises both light reactions and dark reactions (or Calvin cycle).During the dark reactions, carbon dioxide is bound to ribulose bisphosphate, a 5-carbon sugar with two attached phosphate groups, by the enzyme ribulose bisphosphate carboxylase.
