how does the absence of temperature affects the rate of photosynthesis ?

The absence of temperature would significantly affect the rate of photosynthesis. Temperature plays a crucial role in the process of photosynthesis as it directly affects the enzymes involved in the reactions. Most plants have an optimal temperature range for photosynthesis, typically between 15-35 degrees Celsius.

If temperature drops below this optimal range, the enzymes involved in photosynthesis may become less efficient, leading to a decrease in the rate of photosynthesis. Conversely, if temperatures are too high, the enzymes may denature, also slowing down the process.

In the absence of temperature, photosynthesis would not be able to occur as the enzymes would not be able to function properly. This would ultimately lead to a decrease in the production of glucose and oxygen by the plant, which are essential for its survival and growth.
