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.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Transpiration decreases as air becomes drier.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of light.
exposure to excess of CO2.
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.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
What is the source of carbon that is assimilated in photosynthesis?
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
