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.
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.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in soil temperature.
the changes in air temperature.
the changes in CO2 concentration.
Transpiration decreases as air becomes drier.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to excess of CO2.
exposure to shortage of soil moisture.
exposure to high temperature.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Almost half of the total biomass of a tree may be allocated to the roots.
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.
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.
