- a One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
- b An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.
- c A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy.
- d A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen
- e the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
5 Multiple choice questions
- almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
- A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
- process by which plants use the sun's energy to convert water and carbon dioxide into sugars
- One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
- plant capable of synthesizing its own food from simple organic substances
5 True/False questions
C3 Plant → A plant that uses the Calvin cycle for the initial steps that incorporate CO2 into organic material, forming a three-carbon compound as the first stable intermediate.
visible light → The distance between crests of electromagnetic waves.
C4 Plant → type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
stroma → The fluid of the chloroplast surrounding the thylakoid membrane.
photophosphorylation → The process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis.
