Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Transpiration decreases as air becomes drier.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
The annual cycle of photosynthesis mainly follows
the changes in soil temperature.
the changes in light.
the changes in air temperature.
the changes in CO2 concentration.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Almost half of the total biomass of a tree may be allocated to the roots.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
What is the source of carbon that is assimilated in photosynthesis?
In some part of the stems, some photosynthesis may also occur.
Carbon capture is performed by the green parts of plants via 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.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
