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.
Transpiration decreases as air becomes drier.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Almost half of the total biomass of a tree may be allocated to the roots.
In some part of the stems, some photosynthesis may also occur.
The rate of respiration decreases with temperature.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in CO2 concentration.
the changes in air temperature.
the changes in soil temperature.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of CO2.
exposure to shortage of soil moisture.
exposure to excess of light.
What is the source of carbon that is assimilated in photosynthesis?
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.
