Question

osmosis a type of facilitated diffusion uses _______________ to move particles across/through the cell membrane. vesicles membrane proteins nothing (no help) none of the above

Explanation:

Osmosis is a type of passive transport. Facilitated diffusion, including osmosis in some cases, uses membrane - bound proteins (aquaporins for water in osmosis) to help particles cross the cell membrane. Vesicles are used in bulk transport like endocytosis and exocytosis. Osmosis does not occur without any help as water moves through specific membrane proteins.

Answer:

B. Membrane Proteins
