Questions about trees

[peterjeon05]

In large trees, for example, this involves a huge amount of water being pumped over a very long distance. This obviously represents a great deal of work, and that, in turn, requires energy. Wht is the source of this energy, and how is this water pumping operation accomplished???

Hey Peter!

I think you could start to answer that question by researching plant transpiration.

Here are 2 links:

Good luck!

Capillary action........ of Bundal sheath....

I dont know much but I know that "capillary action" is right answer....then.

[MrMistery]

actually no sachin. capillary action does contribute, but the main factor in the ascention of water through xylem in trees is the sucktion of leaves.

[sachin]

That means Leaves are water pumps... right?
And Xylem and bunddles are the pipe lines......

[MrMistery]

something like that yeah...
