Question

To study osmosis, a student placed a thin potato slice in a salt solution. The slice became soft and shriveled. Then, he placed the shriveled slice in water. The slice regained its original shape. Based on the observations, which of these statements is correct? A) The slice regained its shape because salt moved into the potato. B) The potato slice shriveled because water moved from the salt solution into the slice. C) The potato slice shriveled because water moved out of the slice into the salt solution. D) The slice regained its shape because the concentration of salt inside and outside the slice became equal.

Answer 1

c

Step-by-step explanation:

Answer 2

The correct option is C.
Osmosis is the process by which water molecules move from the region of lower salt concentration to the region of higher salt concentration, through a semi permeable membrane.
When the thin slice of potato was put inside the salt water, it shrivels because water move out of its cells into the salt solution. When the potato slice was placed in ordinary water, it regained its normal shape because water molecules enter into its cells.
