  2. Photoperiodism - Wikipedia

    en.wikipedia.org/wiki/Photoperiodism

    A short-day plant will not flower if light is turned on for a few minutes in the middle of the night and a long-day plant can flower if exposed to more red-light in the middle of the night. [9] Cryptochromes are another type of photoreceptor that is important in photoperiodism.

  3. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

  4. Photorespiration - Wikipedia

    en.wikipedia.org/wiki/Photorespiration

    C 2 photosynthesis (also called glycine shuttle and photorespiratory CO 2 pump) is a CCM that works by making use of – as opposed to avoiding – photorespiration. It performs carbon refixation by delaying the breakdown of photorespired glycine, so that the molecule is shuttled from the mesophyll into the bundle sheath .

    During the photosynthesis shutdown, scientists say that the hottest portions of a tree will have their water-carrying stomata closed off, which kills them. That changes the tree’s canopy ...

  6. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Geological evidence suggests that oxygenic photosynthesis, such as that in cyanobacteria, became important during the Paleoproterozoic era around two billion years ago. Modern photosynthesis in plants and most photosynthetic prokaryotes is oxygenic, using water as an electron donor , which is oxidized to molecular oxygen in the photosynthetic ...

    en.wikipedia.org/wiki/Crassulacean_acid_metabolism

    The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.

  9. Transpiration - Wikipedia

    en.wikipedia.org/wiki/Transpiration

    Many cacti conduct photosynthesis in succulent stems, rather than leaves, so the surface area of the shoot is very low. Many desert plants have a special type of photosynthesis, termed crassulacean acid metabolism or CAM photosynthesis, in which the stomata are closed during the day and open at night when transpiration will be lower.
