Transpiration decreases as air becomes drier.
In some part of the stems, some photosynthesis may also occur.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in light.
the changes in air temperature.

Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Carbon capture is performed by the green parts of plants via photosynthesis.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
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.
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?
