Passive absorption

Vedclass · Answer

(C) The movement of mineral ions into plant root cells can occur through two main processes: active and passive transport.Passive absorption refers to the movement of ions across the cell membrane along the concentration gradient without the expenditure of metabolic energy $(ATP)$.Since diffusion is a passive process that occurs from a region of higher concentration to a region of lower concentration,the movement of mineral ions into root cells via diffusion is termed passive absorption.Osmosis is the movement of water molecules,imbibition is the absorption of water by solid particles,and endocytosis is a bulk transport mechanism,none of which describe the diffusion of mineral ions.

The movement of mineral ions into plant root cells as a result of diffusion is called.
