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.
The rate of respiration decreases with temperature.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to high temperature.
exposure to excess of light.
exposure to shortage of soil moisture.
The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Carbon capture is performed by the green parts of plants via photosynthesis.
Almost half of the total biomass of a tree may be allocated to the roots.
As plants respire, they release
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
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.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
What is the source of carbon that is assimilated in photosynthesis?
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
