The rate of respiration decreases with temperature.
What is the source of carbon that is assimilated in 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 soil temperature.
the changes in air temperature.
As plants respire, they release
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
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.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
