Question

The water potential and osmotic potential of pure water are
A) 100 and 0
B) 0 and 0
C) 100 and 200
D) 0 and 100

Answer 1

The potential energy of water per unit volume is the water potential. The minimum pressure that needs to be applied to a solution to avoid the inward movement of its pure solvent through a semipermeable membrane is osmotic pressure. The propensity of water to move from one region to another is quantified as water potential because of osmosis, mechanical strain, gravity, and capillary action.

Complete answer: By convention, the water potential of pure water is zero and the osmotic potential of pure water is also zero since dissolved salts are not present. If there are any solute particles in the solution, only some osmotic potential can grow. Water potential is water's chemical potential, which depends on the number of molecules of water in the solution. The greater the number of molecules of water in the solution, the greater the capacity for water. The flow of water is integrated by the water potential, either in the same or different direction. There are many factors influencing the potential difference within any biological system, such as the addition of solutes decreases the potential and the rise in pressure raises the potential. - Water can shift, in simple terms, from higher potential areas to lower potential areas. Like water with dissolved salt, it has a lower potential compared to pure water, which means it has a negative water potential. Now, it can be inferred from the above knowledge that the water potential of pure water is zero and that the osmotic pressure is also zero since there is no dissolved salt in pure water. If there are any solute particles, the water potential is present in the water and the osmotic potential is produced and it increases accordingly. The water potential of pure water is considered to be zero by convention so that the water potential of all alternatives is negative. The potential caused by dissolved solutes is the osmotic potential. The higher the number of solute particles dissolved, the greater the osmotic potential. The number of dissolved solute particles is zero in pure water, so the osmotic potential is zero.
Thus, the correct answer is option B.

Note: For direct and indirect purposes, water may be used. Showering, drinking, and cooking are direct uses, while the use of water in the processing of wood for making paper and in the manufacture of steel for automobiles are examples of indirect purposes. Agriculture, industry, and energy production are the majority of the world's water consumption.
