Hint: They are the processes that involve the filtration of water and the movement of water across the semi-permeable membranes.
Complete answer:
Osmotic pressure is defined as the pressure required to completely stop the entry of water into an osmotically active solution across a semipermeable membrane. The movement of water will be from the low osmotic pressure to the high osmotic pressure region. This atmospheric pressure can be measured in various units including atmospheres, pascals, or bars.
The potential of the movement of water from the hypotonic solution (concentration of solvent in=s more) to the hypertonic solution (concentration of the solute is more) through a semipermeable membrane is known as the osmotic potential. The solute is completely absent in the pure water leading to the osmotic potential to be zero.
The osmotic potential (solute potential) is made possible due to the presence of both inorganic and organic solutes in the soil solution. The freedom of the movement of the water is lowered when it is surrounded by the ions, these ions and solutes clump around the water molecule resulting in the potential energy to be lowered.
Osmotic pressure is numerically equivalent to osmotic potential but the osmotic potential has a negative value, while osmotic pressure has a positive value.
So, the correct answer is ‘Assertion is correct but Reason is incorrect'.
Note: In humans, the body has homeostatic or regulatory mechanisms that help to maintain the osmotic pressure and the volume of the extracellular water with physiological limits. Osmoregulation maintains the proper balance of electrolytes in the human body, despite external factors like temperature, diet, and weather conditions. The optimal concentration is maintained in the cell by maintaining the osmotic balance of the electrolytes and non-electrolytes. This balance is maintained in all the tissues and body organs by the diffui]sion of the water molecules and solutes.
