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.
Carbon capture is performed by the green parts of plants via photosynthesis.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
What is the source of carbon that is assimilated in photosynthesis?
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.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Almost half of the total biomass of a tree may be allocated to the roots.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
soil moisture (REW).
air temperature (T).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
In some part of the stems, some photosynthesis may also occur.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Plants open its stomata to avoid losing too much water.
