JasonElliotttransport that doesn't need ATP; across gradientsdecrease weight of celery due to loss of watercelery will absorb water and gain weight

Jeffrey ScottNuttallWhen molecules move through a tissue or other substance due to osmosis or other phenomena that do not require any active propulsion or moving parts on the part of the substrate it's moving through.7.45.87.768.36.12.62.82.6The samples in the saltwater should weigh LESS than they did initially because some of the water from the celery's tissues will pass out of the celery due to osmosis (to "balance" the concentration of salt in the surrounding water).The samples in the pure water should weigh MORE than they did before... though possibly not much more, depending on how pure the water actually is and how high the concentration of chemicals is in the fluids inside the celery's tissues.7.15.986.57.963.142.6
