Photobiology

Example:Studies in photobiology have shown that light intensity directly affects the efficiency of photosynthesis in plants.

Definition:The process through which green plants, some bacteria, and algae convert light energy into chemical energy which can later be released to fuel the organisms' activities (usually by converting water, carbon dioxide, and solar energy into glucose and oxygen).

Example:Research in photobiology has demonstrated how exposure to certain wavelengths of light can reset circadian rhythms in humans.

Definition:A natural, internal physiological cycle that regulates the sleep-wake cycle and repeats roughly every 24 hours.

Example:Scientists are investigating how different types of photoresponse can help plants adapt to changing environmental conditions.

Definition:A biological reaction to light, which can be studied in the context of photobiology.
