Can photosynthesis only take place in light?

No, this is a 24-hour phenomenon.

Plant photosynthesis is a process in which, under the influence of light absorbed by plant chlorophylls, organic matter is formed from inorganic (water and carbon dioxide), which in turn ultimately provides plants with the nutrients they need. Thanks to these complex reactions, human life on Earth is also supported.

It is divided into two stages: light and dark stages. They are closely interconnected.

The light phase can only occur in the light, the place of implementation: the inner membranes of chloroplasts. It carries with it a complex of complex processes: capturing the energy of the sun, storing it and using it for recovery.

The dark phase occurs in the stroma of chloroplasts. With it, oxygen is released and glucose is synthesized. The last factor is performed continuously and does not require the presence of light, since the already stored light energy is used. Thus, the dark phase lasts both day and night.
