9. Transport Across Membranes

In a cell-biology context, which statement correctly describes how water moves via osmosis across a selectively permeable membrane?

In the context of passive transport (diffusion and osmosis), what happens to an animal cell placed in an isotonic solution relative to its cytosol?

In passive transport, the principal force driving net movement of molecules during diffusion across a membrane is the:

Facilitated diffusion moves substances across a membrane via specific transport proteins. Is facilitated diffusion an active or passive transport process?

An animal cell is placed in a hypertonic solution relative to its cytosol. Which outcome is most likely due to osmosis?

In cell biology, what is diffusion?

In cell biology, osmosis refers to the movement of which substance across a selectively permeable membrane?

Which statement best describes how water moves during osmosis across a selectively permeable membrane?

An Elodea leaf cell is placed in a hypertonic solution relative to its cytoplasm. Which outcome best describes what will happen due to osmosis?

In passive transport by simple diffusion, how does the magnitude of the concentration gradient across a membrane affect the net rate of diffusion (all else equal)?

Which statement best describes the difference between osmosis and diffusion in passive transport?

In the context of passive transport, osmosis is defined as the movement of which substance across a selectively permeable membrane?

During osmosis across a selectively permeable membrane, which molecule does NOT move across the membrane (assuming only water can pass)?

In cell biology, osmosis can be defined as which of the following?

In passive transport, how does increasing the distance a molecule must travel (diffusion path length) affect the rate of diffusion across a medium when all other factors remain constant?
