Photosynthesis primarily takes place during daylight hours, when sunlight is available. This process occurs in green plants, algae, and some bacteria, using light energy to convert carbon dioxide and water into glucose and oxygen.
More specifically, photosynthesis typically peaks during the early to late morning hours and continues into the afternoon. The intensity of sunlight is crucial for photosynthesis, as it is the light energy that drives the chemical reactions. However, it is important to note that some plants exhibit variations based on their specific adaptations. For instance, certain plants known as CAM (Crassulacean Acid Metabolism) plants, like succulents, perform photosynthesis at night to reduce water loss in arid conditions.
In summary, while photosynthesis occurs during the day, the exact timing can vary depending on the type of plant and environmental factors.
