Question

which of the following best describes the type of transport that is occurring? osmosis, because water is moving across the cell membrane going with the concentration gradient osmosis, because water is moving across the cell membrane going against the concentration gradient diffusion, because water is moving across the cell membrane going with the concentration gradient diffusion, because water is moving across the cell membrane going against the concentration gradient

Explanation:

Osmosis is the movement of water across a semi - permeable membrane (like the cell membrane) from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration), which is with the concentration gradient. Diffusion is the movement of solutes (not water in this case as the question is about water movement).

Answer:

Osmosis, because water is moving with the concentration gradient.
