To transform atmospheric CO2 into organic molecules, plants can use the energy from
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Transpiration decreases as air becomes drier.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of CO2.
exposure to excess of light.
exposure to shortage of soil moisture.
The rate of respiration decreases with temperature.
Almost half of the total biomass of a tree may be allocated to the roots.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
What is the source of carbon that is assimilated in photosynthesis?
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
air temperature (T).
soil moisture (REW).
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
