question 17
2 points
diffusion of water through a semipermeable membrane is called
a active transport
b osmosis
c diffusion
d endocytosis
e facilitated diffusion

Explanation:

• Active transport: Requires energy (ATP) to move substances against a concentration gradient. Not related to water diffusion.
• Osmosis: Specifically the diffusion of water through a semi - permeable membrane.
• Diffusion: General movement of substances (not just water) from high to low concentration.
• Endocytosis: Process of a cell engulfing large particles.
• Facilitated diffusion: Movement of substances (usually larger or polar) through transport proteins, but not specific to water.

Answer:

B. osmosis
