How can 100 meter trees uptake water?

Answer 1

Capillary action and the nature of nutrients and water underground are reasons why 100 meter trees can uptake water. Capillary action is the reverse of gravity, which keeps things earth born and grounded. Gravity works downward whereas capillary action works upward.

Additionally, nutrients and water underground aren't comfortable with their minimal or no presence elsewhere. So nutrients and water cooperate in moving out of the soil where they're present, and into tree roots and up tree trunks where they're not.
