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.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to high temperature.
exposure to excess of light.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
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.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
the total leaf area (LAI).
air temperature (T).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
The annual cycle of photosynthesis mainly follows
the changes in air temperature.
the changes in soil temperature.
the changes in light.
the changes in CO2 concentration.
What is the source of carbon that is assimilated in photosynthesis?
Carbon capture is performed by the green parts of plants via photosynthesis.
Transpiration decreases as air becomes drier.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
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.
As plants respire, they release
