Transpiration decreases as air becomes drier.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
What is the source of carbon that is assimilated in photosynthesis?
Carbon capture is performed by the green parts of plants via 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 air temperature.
the changes in light.
the changes in soil temperature.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
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.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of light.
exposure to excess of CO2.
exposure to shortage of soil moisture.
