To transform atmospheric CO2 into organic molecules, plants can use the energy from
When there is low soil moisture, plants close its stomata pores which then decreases 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.
What is the source of carbon that is assimilated in photosynthesis?
As plants respire, they release
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
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.
Transpiration decreases as air becomes drier.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to excess of light.
exposure to high temperature.
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.
Plants open its stomata to avoid losing too much water.
