The rate of respiration decreases with temperature.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Almost half of the total biomass of a tree may be allocated to the roots.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
air humidity (VPD).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
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.
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.
What is the source of carbon that is assimilated in photosynthesis?
