At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
To transform atmospheric CO2 into organic molecules, plants can use the energy from
In some part of the stems, some photosynthesis may also occur.
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.
What is the source of carbon that is assimilated in photosynthesis?
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
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.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of light.
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.
