How does water move through plants to get to the top of tall trees? Here we describe the pathways and mechanisms driving water uptake and transport through plants, and causes of flow disruption.

Under normal circumstances, the rate of water uptake gives a measure of the rate of transpiration. A simple potometer is a piece of capillary tubing to which a plant has been connected.

4. Plant water relations- Effects of various abiotic stresses on a) water potential, b) transpiration rate and c) stomatal density in bean plants. 5. Mineral nutrition - Effects of phosphorous ...
