As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
What is the source of carbon that is assimilated in photosynthesis?
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in CO2 concentration.
the changes in air temperature.
the changes in soil temperature.
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.
