Vedclass · Answer

(B) Permeable transport (such as diffusion or osmosis) typically involves the movement of individual molecules or ions across a membrane based on their concentration gradient and their ability to pass through the membrane structure (permeability). In contrast,bulk transport (or mass flow) involves the movement of substances in bulk from one point to another as a result of pressure differences between the two points. This process is independent of the individual properties of the molecules being transported; rather,it depends on the solvent system (the medium in which substances are dissolved) and the physical force (pressure) acting on the entire bulk of the fluid. Therefore,the fundamental difference relates to the solvent system as well as the structure of molecules involved in the transport process.

Column-$I$	Column-$II$
$(a)$ Passive transport	$(p)$ Movement from higher concentration to lower concentration, no energy required
$(b)$ Active transport	$(q)$ Movement along the concentration gradient, requiring carrier proteins
$(c)$ Facilitated diffusion	$(r)$ Movement against the concentration gradient, requiring energy
$(d)$ Osmosis	$(s)$ Diffusion of solvent molecules across a semi-permeable membrane
