Ch.10 Photosynthesis Flashcards
In C4 plants, a type of photosynthetic cell arranged into tightly packed sheaths around the veins of a leaf
Bundle-Sheath Cell
An organism that obtains organic food molecules w/o eating other organism or substances derived from other organisms
Autotrophs
A green pigment located in the membranes w/in the chloroplasts of plants & algae & in the membranes of certain prokaryotes
Chlorophyll
The second of two major stages in photosynthesis involving fixation of atmospheric CO2 & reduction of the fixed carbon into carbs
Calvin Cycle
The initial incorporation of carbon from CO2 into an organic compound by an autotrophic organism
Carbon Fixation
A photosynthetic pigment that participates directly in the light reactions, which convert solar energy to chemical energy
Chlorophyll a
An accessory photosynthetic pigment that transfers energy to chlorophyll a
Chlorophyll b
An accessory pigment, either yellow or orange, in the chloroplast of plants & in some prokaryotes
Carotenoids
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
C3 Plant
A plant in which the Calvin Cycle is preceded by reactions that incorporate CO2 into a four-carbon compound, the end product of which supplies CO2 for the Calvin Cycle
C4 Plant
A plant that uses Crassulacean acid metabolism, an adaption for photosynthesis in arid conditions
CAM Plant
An organism that obtains organic food molecules by eating other organisms or substances derived from them
heterotroph
Leaf cells specialized for photosynthesis
Mesophyll
The conversion of light energy to chemical energy that’s stored in sugars or other organic compounds
Photosynthesis
The process of generating ATP from ADP & phosphate by means of chemiosmosis, using a proton-motive force generated across the thylakoid membrane of the chloroplast or the membrane of certain prokaryotes during the light reactions of photosynthesis
Phosphorylation
