Osmosis
B
Diffusion
C
Active transport
D
Facilitated diffusion
Verified step by step guidance
1
Identify the key concept: The problem is asking about the passive movement of molecules from areas of high concentration to low concentration.
Understand the term 'passive movement': This refers to the movement of molecules without the use of energy.
Review the options provided: Osmosis, Diffusion, Active transport, and Facilitated diffusion.
Eliminate options that do not fit the definition of passive movement: Active transport requires energy, so it is not a passive process.
Recognize that 'Diffusion' is the process where molecules move from an area of high concentration to an area of low concentration without the use of energy, fitting the definition of passive movement.
