Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
As plants respire, they release
The rate of respiration decreases with temperature.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
In some part of the stems, some photosynthesis may also occur.
Carbon capture is performed by the green parts of plants via photosynthesis.
Transpiration decreases as air becomes drier.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
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.
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.
