3 Explain the role of water potential in the movement of water from soil trough the plant and into the air?

Answer 1

thanks!!!!!!!!!!

Answer 2

اب در گیاه به سه علت جابه جا میشود یکی مکش منفی ریشه است.دیگری پتانسیل مثبت اب در اوندهاو سوم مکش از بالا به علت خروج اب از روزنه هابه صورت بخارومایع

Answer 3

The water is taken in by osmosis through the root-hair cells. The water then passes to the xylem tissue in the middle of the root and travels up the stem via the same xylem tissue. From the xylem in the leaf it passes through the air spaces and out into the atmosphere through the stomata.

Answer 4

Osmosis is actually dependent to water potential i.e. movement is from area of higher potential to area of lower potential. The absorption of water by the roots is dependent to transpiration. As the water evaporates in the stomates this creates a lower potential in the roots so that water will diffuse via osmosis
