"Stage of acclimation" refers to the seasonality of
the litter fall activity.
the flowering activity.
the growth activity.
the photosynthetic activity.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Då VPD ökar blir assimilationen långsammare eftersom växten tillsluter sina klyvöppningar.
Respiration is a cellular process to obtain chemical energy from
the oxidation soil nutrients.
the oxidation of plant tissues.
the oxidation of organic molecules.
the oxidation of water.
Since stomata are the same pores through which carbon dioxide enters into the leaves, the result of their closure is a reduction 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.
Eftersom koldioxid kommer in i växten genom klyvöppningarna går assimilationen långsammare då klyvöppningarna tillsluts.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of light.
exposure to high temperature.
exposure to excess of CO2.
In trees, approximately half of the carbon bound in photosynthesis is used for construction of new biomass.
The stage of acclimation at any given day depends on the temperatures experienced by the plant during the previous months.
The stage of acclimation at any given day depends on the temperatures experienced by the plant during the previous days.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
The air is moist if VPD (Vapour Pressure Deficit) is high.

As VPD increases, photosynthesis decreases due to the closure of the stomata.
