NEET BIOLOGY

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: -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-3: -Respiration in plants happens throughout the day and night thereby carbon dioxide is produced. However, during the daytime, the amount of carbon dioxide released is negligible compared to the amount of oxygen produced as a result of photosynthesis. Hence, one should not sleep under a tree at night.

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: -Photosynthesis occurs only during daytime since sunlight is an important component of the same. Whereas, respiration is a continuous process that takes place at day and night.
