What is the source of carbon that is assimilated in photosynthesis?
Transpiration decreases as air becomes drier.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
The rate of respiration decreases with temperature.
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
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.
Almost half of the total biomass of a tree may be allocated to the roots.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
