2. Light and plants
Plants use light energy for heating and photosynthesis, but also as a synchronization signal to trigger certain physiological processes (photomorphogenesis) such as flowering, foliage or stem development, or germination.
From a physiological point of view, photosensitive proteins called "photoreceptors" perform the functions of photosynthesis and photomorphogenesis. There are two types of photoreceptor: photosynthetic pigments, whose role is to capture light energy for photosynthesis, and photosensory receptors, which trigger photomorphogenesis.
2.1 Photosynthetic pigments
Photosynthetic pigments perform two functions: active pigments convert light energy into chemical energy, while accessory pigments, also known as "secondary pigments",...
