understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses.
-related to the rate of photosynthesis. combination of carbon dioxide and water ---sunlight (enzyme reaction) --> glucose and oxygen.
-glucose is turned into starch and is stored in the plant.
-increasing carbon dioxide. CO2 is the substrate.
-rate of reaction (photosynthesis) will increase if we increase the carbon dioxide level until a certain point
-will produce a higher yield up to a point until maximum yield.
-increase the temperature.
-rate of photosynthesis and temperature graph.
-increase in temperature the rate of photosynthesis will increase --> yield will increase.
-when we hit the peak on graph -> optimum temperature.
-increase carbon dioxide and increase in temperature there will be an increase in photosynthesis therefore the yield but they both have limits.
-increasing temp in a greenhouse will have other affects such as avoiding frost damage and providing constant temperature - contribute to increased yield.
