Carbon becomes locked as part of the accumulating plant biomass as plants grow.
What is the source of carbon that is assimilated in photosynthesis?
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Carbon capture is performed by the green parts of plants via photosynthesis.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of CO2.

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
photosynthetically active solar radiation (PAR).
soil moisture (REW).
air humidity (VPD).
the total leaf area (LAI).
air temperature (T).
Transpiration decreases as air becomes drier.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
The rate of respiration decreases with temperature.
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.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
