... all sorts of factors. In the autumn of temperate zones, ponds "turn over": as oxygen-rich surface water cools, it becomes more dense and sinks; deeper water replaces it, picks up oxygen from the air, cools and sinks; when the whole pond is at 4 degrees C, the turnover stops (below that ...

Hey thanks, I ended up concluding that most respiration is occuring at shoot and root apical meristems, or other photosynthate "sinks", whereas the leaves are "sources". This would explain the lack of respiration in the leaves (or lack of relationship to leaf area), as ...

Density changes can be observed by watching whether a drop of the original solution floats or sinks in the test solution after tissue incubation. Alternately, for a more accurate measurement of changes in the solution density, a refractometer ...
