Very urgent. The medium surrounding the cell has higher concentration of water than inside the cell. What can you comment about the direction of diffusion, and the type of medium?
(A) Water from the medium diffuses into the cell: Hypotonic medium
(B) Water from the cell diffuses out of the cell: Hypertonic medium
(C) Water from the medium diffuses into the cell: Hypertonic medium
(D) Water from the cell diffuses out of the cell: Hypotonic medium
pls tell fast. i mill follow, like and mark brainliest whoever answers the question.

Answer:
A.Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. ... Cells placed in a hypotonic solution will take in water across their membrane until both the external solution and the cytosol are isotonic.
B.In hypertonic solutions, water diffuses out of the cell due to osmosis and the cell shrinks. Thus, the animal cell has always to be surrounded by an isotonic solution.
C.If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell
D.If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.
