Describe why high temperature increases photorespiration in C3 plants (Hint: your answer should involve stomata and carbon dioxide). How do C4 plants avoid photorespiration?
Homework Answers
At high temperature , the solubility of carbon dioxide in stroma decreases and thus more oxygen is available in the stroma for photorespiration.Thus RuBisco fixes more oxygen than carbon dioxide causing photorespiration. In C4 plant , carbon fixation occurs in two stage - first stage occurs in mesophyll cell where carbon dioxide is fixed using phosphoenol pyruvate into a four carbon compound . This 4 carbon compound moves to bundle sheath where second stage occurs and releases carbon dioxide thus concentrating carbon dioxide in bundlesheath cell .

. Describe why CAM plants have an advantage over C3 plants in the desert and why C4 plants have an advantage over C3 plants in tropical climates. (Be sure to discuss the relevance of photosynthetic enzymes and their location, photorespiration, water use efficiency, and stomatal behavior and leaf anatomy.) 4. Thinking about anatomy, morphology, and “behavior” describe ways that plant leaves are adapted to intercepting light, increasing CO2 diffusion while reducing water loss. 5. In general terms, describe the characteristics...
