EVERYDAY SCIENCE

Detailed explanation-1: -Respiration occurs all through the day, but the photosynthesis process occurs in the daytime, in the presence of sunlight only. Consequently, respiration becomes evident at night time in plants.

Detailed explanation-2: -Plant respiration occurs 24 hours per day, but night respiration is more evident since the photosynthesis process ceases. During the night, it is very important that the temperature is cooler than during the day because plants can experience stress.

Detailed explanation-3: -Plants respire both during day and by night. However, during the day, the amount of oxygen given out by the plant through the process of photosynthesis far exceeds the amount of oxygen used by the plant for respiration.

Detailed explanation-4: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-5: -(c) Respiration takes place both during day and night.
