As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to high temperature.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
In some part of the stems, some photosynthesis may also occur.
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
The rate of respiration decreases with temperature.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Transpiration decreases as air becomes drier.
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.
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
