Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens to the process of photosynthesis at night?
A
the process slows down / stops
B
the process speeds up
C
the process still continues at regular speed
Explanation: 

Detailed explanation-1: -At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen. The compensation point is where the net change in oxygen is zero. The rate of respiration is fairly constant, while photosynthesis is light-dependent.

Detailed explanation-2: -If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days–or in some cases, a few weeks–how long they lived would largely be a factor of how much sugar they had stored within their cells.

Detailed explanation-3: -Temperature-If it gets too cold the rate of photosynthesis will slow right down. If it gets too hot then plants cease to be able to photosynthesise.

Detailed explanation-4: -Temperature has an impact on the rate of photosynthesis. The rate of photosynthesis increases as the temperature rises. During photosynthesis, a temperature of more than 40 °C slows down the process. Because it is an enzyme-controlled process, this is the case.
