4.Sam and John were arguing in a group about osmosis. Sam said that osmosis is when water moves across a cell membrane from an area of higher concentration to an
area of lower concentration. John says that it is when water moves across a cell
membrane but from lower concentration to higher concentration. Who is correct and
why are they correct? (S7L2a)
A. John is correct because he said that water is moved across the cell membrane
and then describes active transport and osmosis is an example of active
transport
B. Sam is correct because he said that water moves across a cell membrane from
an area of high concentration to lower concentration,
C. John is correct because he said that water moves from lower concentration to
higher concentration.
D. Neither is correct because osmosis has nothing to do with water
