Question

ASSERTION: Diffusion is a passive type of transport.
REASON: Osmosis is an active process of membrane transport.

B. Both Assertion & Reason are true but Reason is not a correct explanation of the Assertion.
C. Assertion is True but the Reason is False.
D. Both Assertion & Reason are false.

Answer 1

Diffusion and osmosis are two different processes that occur to equalize the concentration of two solutions. In addition, the movement of the particles (which are solute and solvent) from one part to a different one through a membrane is called osmosis whereas diffusion is just the movement of particles from higher to lower concentration gradients.

Complete answer:
Diffusion may be defined as a method within which the molecules spread because of their mechanical energy(in this case kinetic energy) and movement of molecules is from higher concentration to lower concentration. In the diffusion method, the solute and solvent move to equalize the concentration of that particular solution. The process of diffusion doesn't need energy and so it's passive transport. Osmosis is a method within which the solvent molecules move from lower matter concentration to higher matter concentration through a semipermeable membrane. This method doesn't need energy.

Thus, the right answer is C-Assertion is True but the Reason is False

Additional information:
A gradient is an imbalance in concentration, and moving down a gradient simply means the particle is attempting to be equally distributed all over, like dropping food color in water. This can be what happened after we created our dry cereal - a bunch of separate ingredients came along and displayed across the complete mixture. We tend to decide this out moving “downhill”, and it doesn’t need energy.
Simple diffusion is just as precisely what it seems like – molecules move down their gradients through the membrane. Molecules that observe easy diffusion should be little and nonpolar, to pass the membrane.

Note: The molecule possibly to be concerned in simple diffusion is water - it will simply go through cell membranes. Once water undergoes simple diffusion, it's called osmosis. Facilitated diffusion is diffusion that helps (facilitated by) a membrane transport channel. These channels are glycoproteins (proteins with carbohydrates attached) that enable molecules to tolerate the membrane.
