As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
The rate of respiration decreases with temperature.
In some part of the stems, some photosynthesis may also occur.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Transpiration decreases as air becomes drier.
Carbon capture is performed by the green parts of plants via photosynthesis.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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 light.
the changes in CO2 concentration.
the changes in air temperature.
the changes in soil temperature.
