  2. Carbon dioxide sensor - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_sensor

    For exhaust gas analysis, where CO2 sensors are used to quantify the CO2 from combustion engine exhausts to help improve and tune engine efficiency. [15] For biological incubators where CO2 sensors in biological incubators help control and confirm that CO2 levels remain between 5-10%, which is essential for maintaining proper pH in culture ...

  3. Compensation point - Wikipedia

    en.wikipedia.org/wiki/Compensation_point

    The CO 2 compensation point (Γ) is the CO 2 concentration at which the rate of photosynthesis exactly matches the rate of respiration. There is a significant difference in Γ between C 3 plants and C 4 plants: on land, the typical value for Γ in a C 3 plant ranges from 40–100 μmol/mol, while in C 4 plants the values are lower at 3–10 μmol/mol. Plants with a weaker CCM, such as C2 ...

  4. Free-air concentration enrichment - Wikipedia

    en.wikipedia.org/wiki/Free-air_concentration...

    FACE facility in the Nevada desert. Free-Air Carbon dioxide Enrichment (FACE) is a method used by ecologists and plant biologists that raises the concentration of CO 2 in a specified area and allows the response of plant growth to be measured.

  5. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Through photosynthesis, plants use CO 2 from the atmosphere, water from the ground, and energy from the sun to create sugars used for growth and fuel. [22] While using these sugars as fuel releases carbon back into the atmosphere (photorespiration), growth stores carbon in the physical structures of the plant (i.e. leaves, wood, or non-woody stems). [23]

  6. Photosynthesis system - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis_System

    Photosynthesis systems function by measuring gas exchange of leaves.Atmospheric carbon dioxide is taken up by leaves in the process of photosynthesis, where CO 2 is used to generate sugars in a molecular pathway known as the Calvin cycle.

  7. Greenhouse - Wikipedia

    en.wikipedia.org/wiki/Greenhouse

    When the inside of a greenhouse is exposed to sunlight, the temperature increases, providing a sheltered environment for plants to grow even in cold weather. The terms greenhouse, glasshouse, and hothouse are often used interchangeably to refer to buildings used for cultivating plants. The specific term used depends on the material and heating ...

  8. Greenhouse gas monitoring - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_monitoring

    Concentrations in ppm of the major greenhouse gases between 1978 and 2010. Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry.

  9. Respirometer - Wikipedia

    en.wikipedia.org/wiki/Respirometer

    A respirometer is a device used to measure the rate of respiration [1] of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. [2] They allow investigation into how factors such as age, or chemicals affect the rate of respiration. [3]
