• Question

  From your most recent response: "water loss of the apical organs". What exactly do you mean by this phrase? To my crude understanding, you seem to be suggesting that the leaf buds suck. Really? A fifty foot column of sap solution? That is one muscular leaf bud!

  Answer

  Dear porphyry5, it is likely time for you to either (1) research this topic on your own or (2) speak to a plant physiologist. There are different mechanism for sap rising in trees. For example, maples have a kind of "carbon dioxide pump", which you can easily find descriptions of online. However, I'm not certain you will be satisfied with the short answers being provided here. As to your last response, I did not write that suction pulls the water up the tree. Please read over the response carefully. Best wishes.
