What are the water potential and osmotic pressure of pure water?

Pressure potential is usually ........... and it is denoted as

$A$ $0.1 \ M$ solution of a solute has a water potential of:

What is the relationship between pure water and water potential?

How many of the following statements are correct?
$I -$ Water molecules possess kinetic energy.
$II -$ In liquid and gaseous forms,water molecules are in random motion.
$III -$ In liquid and gaseous forms,the motion of water molecules is slow and constant.
$IV -$ If a system has a higher quantity of water,its water potential is higher.
$V -$ Pure water has the lowest water potential.
$VI -$ Water always moves from a region of higher water potential to a region of lower water potential.

When water is lost through transpiration from the leaves, what happens to the water potential of the leaf cells?
