What is the term for the diffusion of water across a semipermeable membrane?
A
Active transport
B
Osmosis
C
Diffusion
D
Facilitated diffusion
Verified step by step guidance1
Identify the key concept: The problem is asking about the movement of water across a semipermeable membrane.
Understand the term 'semipermeable membrane': A semipermeable membrane allows certain molecules or ions to pass through it by diffusion and occasionally specialized 'facilitated diffusion'.
Recognize the process: The diffusion of water across a semipermeable membrane is specifically known as 'osmosis'.
Differentiate from other processes: Active transport requires energy to move substances against a concentration gradient, while facilitated diffusion involves the use of transport proteins to move substances across membranes without energy input.
Conclude with the correct term: The correct term for the diffusion of water across a semipermeable membrane is 'osmosis'.
