Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to excess of light.
exposure to high temperature.
exposure to shortage of soil moisture.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
In some part of the stems, some photosynthesis may also occur.
The rate of respiration decreases with temperature.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
As plants respire, they release
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Carbon capture is performed by the green parts of plants via photosynthesis.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
The annual cycle of photosynthesis mainly follows
the changes in soil temperature.
the changes in light.
the changes in air temperature.
the changes in CO2 concentration.
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
air temperature (T).
air humidity (VPD).
