Question

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


A
Osmosis
loader
B
Passive absorption
loader
C
Active absorption
loader
D
Endocytosis
loader

Solution

The correct option is B Passive absorption
Osmosis is a phenomenon where a solvent is transferred from its higher concentration to its lower concentration via a semipermeable membrane. Endocytosis occurs when the solvent move inside the cell( from its higher concentration to its lower concentration). Molecules or ions diffused from a region of their higher concentration to a region of their lower concentration.  This movement of mineral ions into root cells as a result of diffusion is called passive absorption. 

So, the correct option is 'passive absorption'
