Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
In some part of the stems, some photosynthesis may also occur.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
The rate of respiration decreases with temperature.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
What is the source of carbon that is assimilated in photosynthesis?
Transpiration decreases as air becomes drier.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Almost half of the total biomass of a tree may be allocated to the roots.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
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.
