Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in soil temperature.
the changes in air temperature.
the changes in light.
The rate of respiration decreases with temperature.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
air temperature (T).
the total leaf area (LAI).
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of light.
exposure to excess of light
exposure to high temperature
exposure to excess of CO2

Carbon capture is performed by the green parts of plants via photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
What is the source of carbon that is assimilated in photosynthesis?
