environmental influences have a noticeable effect on the state of the activity of PSA (photosynthetic apparatus) of plants. Large changes in the activity of the photosynthetic apparatus are observed at very high and low temperatures.

When studying the mechanism of this process, it showed phytochrome activation and an increase in the amount of chlorophyll inside the cell
