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.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Carbon capture is performed by the green parts of plants via photosynthesis.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to excess of CO2.
exposure to high temperature.
exposure to shortage of soil moisture.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Transpiration decreases as air becomes drier.
Almost half of the total biomass of a tree may be allocated to the roots.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
What is the source of carbon that is assimilated in photosynthesis?
In some part of the stems, some photosynthesis may also occur.
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.
