Why does correlation not prove causation

Could be a coincidence and there may be other contributing factors

How does water move from the soil to the leaves of a plant

The water moves through the plant by transpiration. The water is absorbed through the root hair cells by osmosis as there is a higher water potential in the soil to the area of low water potential in the root hair cells across a semi-permeable membrane. The root hair cell is adapted for fast osmosis by having projections to increase surface area. Thr water is pulled up the xylem in the transpiration stream.
