In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
What is the source of carbon that is assimilated in photosynthesis?
Carbon capture is performed by the green parts of plants via photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Almost half of the total biomass of a tree may be allocated to the roots.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
