When does photosynthesis typically not occur in plants?

Photosynthesis typically does not occur in plants during the night because this process requires sunlight. During the day, chlorophyll in the chloroplasts captures light energy, which is then used to convert carbon dioxide and water into glucose and oxygen. This light-dependent reaction is essential for photosynthesis, and without sunlight, the necessary energy source is absent. While photosynthesis can slow down during winter due to shorter daylight hours and lower temperatures, it does not completely cease. In summer, the abundance of sunlight and favorable conditions facilitate active photosynthesis. Thus, the absence of light at night makes it impossible for this process to take place, in line with the requirements of plants for energy to conduct photosynthesis effectively.
