Summary/Abstract: Life on Earth is dependent on several factors. One of them is the light and the reactions taking place with his participation. With the reactions of photosynthesis solar energy is converted into energy of chemical bonds and in this form is transmitted from autotrophic organisms (the producers) to all organisms. The reactions of photosynthesis also produce oxygen, which is necessary for most of the organisms and used in the reactions of cellular respiration. Since plants produce energy and oxygen during the day, whether in this case the night is needed at all. And if so, what are plants doing at night? This paper describes the major physiological and biochemical processes that occur in plants under no access to light, both natural conditions (night) and in the case of artificial darkness. The answer to the question posed in the title is in the description of such processes as photosynthesis, cellular respiration, tropisms, control of the stomata opening/closing and regulation of flowering.
