CAPILLARY ACTION THROUGH CELERY STALK
Fluid absorption is evident in leaves of celery
Surface tension causes the rise of water in a narrow tube. The water is pulled up until the surface tension force along the tube balances the weight of the water in the tube. Plants use capillary to pull water up through their stems.
