In some part of the stems, some photosynthesis may also occur.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
The rate of respiration decreases with temperature.
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Transpiration decreases as air becomes drier.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in soil temperature.
the changes in light.
the changes in air temperature.
the changes in CO2 concentration.
What is the source of carbon that is assimilated in photosynthesis?
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.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon capture is performed by the green parts of plants via photosynthesis.
