Question:
Carbon capture is performed by the green parts of plants via photosynthesis.
Response:
In some part of the stems, some photosynthesis may also occur.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
Plant closes its stomata to avoid losing too much water.
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.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
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
carbon dioxide.
oxygen.
Photosynthesis releases oxygen whereas respiration releases CO2.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
soil heat.
soil nutrients.
sun light.
atmospheric oxygen.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
soil moisture (REW).
atmospheric CO2.
