5 Multiple choice questions
- The fluid of the chloroplast surrounding the thylakoid membrane.
- Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed
- organism that obtains energy from the foods it consumes; also called a consumer
- type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
- 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.
5 True/False questions
photosystem I → One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
Carotenoid → A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
Cyclic electron flow → in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
photorespiration → 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.
Rubisco → plant capable of synthesizing its own food from simple organic substances
