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.
In some part of the stems, some photosynthesis may also occur.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
As plants respire, they release
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Carbon capture is performed by the green parts of plants via photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
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.
The rate of respiration decreases with temperature.
What is the source of carbon that is assimilated in photosynthesis?
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
