Contrast a plant and animal cell. Provide a detailed description of the relevant aspects of stem and root anatomy. Describe some of the fundamental tradeoffs involved in water conduction. Assigned reading Purves et al. Cohesion in water is a result of H-bonding.
Cohesion contributes to the transport of water against gravity.
Water has high surface tension. Diffusion is the result of thermal motion. This is a kind of passive transport. If there is a membrane that won't let a solute pass, the solvent molecules will flow until the concentration is the same on both sides. The pressure needed to keep the volumes the same is the osmotic pressure.
