Water is capable of dissolving a variety of different substances, which is why it is such a good solvent.

And, water is called the "universal solvent" because it dissolves more substances than any other liquid

It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients

“Pakistan would mean a massacre,” the Premier of Punjab Sir Sikandar Hyat Khan predicted to the distinguished civilian Penderel Moon as early as in October 1938 ( Divide and Quit, page 20). That was well before the Muslim League adopted the Pakistan resolution on March 23, 1940, in Lahore, radically altering Sir Sikandar's draft just 24 hours before it was passed. He repudiated it because it dropped the organic linkbetween the two parts of India, which he had provided. He told the Punjab Legislative Assembly, on March 11, 1941, “We do not ask for freedom that there may be Muslim Raj here and Hindu Raj elsewhere. If that is what Pakistan means I will have nothing to do with it.”

Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane. It doen't requires any additional energy to do this work. 

So, Osmosis is a Passive.

Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes.

1. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.

2. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur.

3. Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur.
