When a nutrient moves freely from an area of higher solute concentration into an absorptive cell where the concentration is lower,this is called

Quizplus · Accepted Answer

Passive diffusion is the process in which nutrients move freely from an area of higher concentration to an area of lower concentration, without the need for energy expenditure. In the question, it is specified that the nutrient is moving from an area of higher concentration to a lower concentration, indicating that this is a case of passive diffusion. Facilitated diffusion, on the other hand, involves the use of a protein channel to aid the movement of a nutrient from higher concentration to lower concentration. Active absorption, as the name suggests, requires energy expenditure for nutrients to move against a concentration gradient (from lower concentration to higher concentration). Phagocytosis involves the engulfment of larger particles by a cell, which is not the case here.
