When temperature is increased from minimum to optimum, rate of phosynthesis doubles for every ____ rise in temperature.A. `1^(@)C`B. `10^(@)C`C. `20^(@)C`D. `30^(@)C` |
|
Answer» Correct Answer - B Rate of photosynthesis usually increaes with an increase in temperature upto `40^(@)C` Above this temperature. Rate of photosynthesis starts decreasing due to inactivation of enzyme. The minimum temoperature at which most plants start photosynthesis is `0^(@)-5^(@)C` but it can be as low as `-20^(@)C` for lichens and `-35^(@)C` for some gymnosperms. The maximum temperature at which photosyntheis can occur is `55^(@)C` in some desert plants and `75^(@)C` for hot spring algae. When temperature is increaed from minimum to optimum, the rate of photosynthesis fdoubles for every `10^(@)C` rise in temperature. |
