Ions

I do one with Elodea leaves and saturated salt solutions that works pretty well. The fresh-water aquatic cells are very permeable to water but not so much to the ions, so the cells shrink from osmotic loss. It's simple, easy to set up and for the students ...

the process of transpiration is an active transport. Plants need to constantly keep pumping H+ ions from the stomata cells in order to keep the stomata open. If plant cells ran out of ATP (hypothetically) then all stomata would close and the water column would stop. Therefore, ...

hi , if both ions will move with the same conc and same time then the required conc may not balanced and also as you say both requires different conditions that is ADP and ATP thus they may not pass at the same time.

... was permeable to the same degree to both Na+ and K+, then they would not have to use the ATPase. And since the concentration gradient of both ions are of the same magnitude, then I would expect the ions to move across the membrane at pretty much the same rate (even though K is a bigger atom ...
