9. Transport Across Membranes

Which of the following statements is true of osmosis in cells?

In the context of passive transport, how is osmosis different from diffusion?

When does passive transport occur across a cell membrane?

In passive transport, what is the primary driving force for diffusion of molecules across space or a membrane?

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?
