Retinal

Retinal photosynthesis is the state of the phloem when it is ready to be used as a source of oxygen

If you have ever read about the process of photosynthesis, you may know that the process is the process of producing carbohydrates from carbon dioxide and water in the presence of light. This is a basic example of photosynthetic activity in all plant cells. However, some plant cells have a property called "retinal photosynthesis". In this type of photosynthesis, instead of the usual chlorophyll molecules, other molecules called retinans or retinal pigments are used. Retanal photosynthesis has been known for a long time, but only in recent decades has it begun to attract the attention of biologists. This
