The results summarized in Figure show that the small nectar drop grows at a rate, which, as a first approximation, is nearly independent of the nature of the organic liquid. As the osmolarity of water in the nectar drop continues to decrease due to the dilution of sugar, its growth kinetics slows down and is eventually halted. Let us consider a typical experiment in which we consider a small nectar droplet (0.64 l) of osmolarity of 7.5, which absorbs water and grows. The final volume of this droplet should be about 2 l for its osmolarity in the diluted state to be same as that of salt solution ( 1.2 moles/L). This is in the ball part of what is observed experimentally (Figure ).
