Both Assertion and Reason are false

Detailed explanation-1: -The net force or gradient is determined by the difference in the water potentials of solutions separated by a semipermeable membrane. So, the correct answer is ‘Assertion is correct but Reason is incorrect’.
Detailed explanation-2: -Assertion :Osmosis is a special type of diffusion of water through a semi-permeable membrane. Reason: The net direction and rate of osmosis depends only on the pressure gradient.
Detailed explanation-3: -Complete answer:-Osmosis is a passive process. Hence, the given statement is False.-Osmosis takes place from higher water potential to lower water potential.
Detailed explanation-4: -In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Diffusion can occur in any mixture, including one that includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.
Detailed explanation-5: -Water moves through a semipermeable membrane in osmosis because there is a concentration gradient across the membrane of solute and solvent. The solute cannot effectively move to balance the concentration on both sides of the membrane, so water moves to achieve this balance.
