As plants respire, they release
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.
What is the source of carbon that is assimilated in 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.

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.
Transpiration decreases as air becomes drier.
The rate of respiration decreases with temperature.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in air temperature.
the changes in soil temperature.
the changes in CO2 concentration.
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.
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.
