  2. Photorespiration - Wikipedia

    en.wikipedia.org/wiki/Photorespiration

    CAM plants, such as cacti and succulent plants, also use the enzyme PEP carboxylase to capture carbon dioxide, but only at night. Crassulacean acid metabolism allows plants to conduct most of their gas exchange in the cooler night-time air, sequestering carbon in 4-carbon sugars which can be released to the photosynthesizing cells during the day.

  3. Nyctinasty - Wikipedia

    en.wikipedia.org/wiki/Nyctinasty

    It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [1] Nyctinasty is found in a range of plant species and across xeric , mesic , and aquatic environments, suggesting that this singular behavior may serve a variety of ...

    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.

  5. Plant perception (physiology) - Wikipedia

    en.wikipedia.org/wiki/Plant_perception_(physiology)

    Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...

    As Bryan E. Cummings and Michael S. Waring, the authors of the Drexel study, found, you would need 10–100 plants per square meter to clear the air in the way the NASA study reported.

  7. Photoperiodism - Wikipedia

    en.wikipedia.org/wiki/Photoperiodism

    Other experiments have proven this by exposing plants to extra red-light in the middle of the night. 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]

    "You may find insects like ants in the soil because they’re drawn there by the moisture," says Burke. Signs of underwatering include wilted leaves or leaves with brown spots. "The soil surface ...

  9. 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 ...
