What are the difference between guttation and imbibition?

Mass flow is the movement of substances in bulk as a result of pressure differences between two regions? It is seen for

Match List - I with List - II.
List-I | List-II | ||
(a) | Cohesion | (i) | More attraction in liquid phase |
(b) | Adhesion | (ii) | Mutual attraction among water molecules |
(c) | Surface tension | (iii) | Water loss in liquid phase |
(d) | Guttation | (iv) | Attraction towards polar surfaces |

Which of the following is not take part in the ascent of sap through the xylem in tall plants?


Guttation only occurs in

The structures involved in the process of guttation are:

A submarine has a window of area on its ceiling and is at a depth of below sea level in a sea. If the pressure inside the submarine is maintained at the sea-level atmosphere pressure, then the force acting on the window is (consider density of sea water acceleration due to gravity ):
