comment Is the minicolumn the unit of the neocortex?
Anyone want to suggest an edit to help get answers? Narrowing the question perhaps?

comment How does water move throughout plants?
Indeed it does. There is tension between the weight of the water and the force of the capillary action, which they think is what limits the height of trees (nature.com/nature/journal/v428/n6985/abs/nature02417.html). Remember that the xylem is like a very, very skinny tube, so it isn't like there is a single massive column of water flowing up. With a narrow tube like that, the weight of the water builds pretty slowly.
