In tall trees, which limitation arises because gravitational pull increasingly offsets root pressure, diminishing transpiration?

💡 Explanation

As tree height increases gravitational pull reduces the water potential, causing increased hydraulic resistance/embolisms because tension overcomes cohesive forces disrupting water columns, therefore affecting transpiration, rather than affecting pholem because sugars or nitrogen fixation.
