Carbon becomes locked as part of the accumulating plant biomass as plants grow.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of light.
exposure to high temperature.
exposure to excess of CO2.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
In some part of the stems, some photosynthesis may also occur.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Carbon capture is performed by the green parts of plants via photosynthesis.
Transpiration decreases as air becomes drier.
As plants respire, they release
Almost half of the total biomass of a tree may be allocated to the roots.
Photosynthesis of a tree canopy is driven or influenced by
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
air temperature (T).
air humidity (VPD).
soil moisture (REW).
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in soil temperature.
the changes in CO2 concentration.
the changes in air temperature.
What is the source of carbon that is assimilated in photosynthesis?
To transform atmospheric CO2 into organic molecules, plants can use the energy from
