In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
In some part of the stems, some photosynthesis may also occur.
As plants respire, they release
To transform atmospheric CO2 into organic molecules, plants can use the energy from
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
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.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air temperature (T).
soil moisture (REW).
air humidity (VPD).
The annual cycle of photosynthesis mainly follows
the changes in air temperature.
the changes in CO2 concentration.
the changes in light.
the changes in soil temperature.
Almost half of the total biomass of a tree may be allocated to the roots.
Carbon capture is performed by the green parts of plants via photosynthesis.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
What is the source of carbon that is assimilated in photosynthesis?
