i believe it's D...unicellular organisms but not multicellular organisms must deal with the movement of water by osmosis across their cell membrane.

math2400 · Answer

I don't think it's b cuz the structure of unicellular cells is quite simple while the structure of multicellular cells is quite complex (since they are consist of multiple cells). So unicellular wold need to deal with the movement of water by osmosis..ha took AP Bio last year can't remember exactly how to explain but my best guess is D..
