There is a lower concentration of water outside the cell than inside the cell and the water attracts itself b Water moves from the area of higher concentration outside the cel to the area of lower concentration inside the cell c. The cell membrane is directionaily permeable, so that water can enter the cell membrane but it cannot leave d An infiuxiof wateris needed to maintairn abi con

Explanation / Answer

1. Answer: Option B is correct.

Explanation:

Water potential of pure water is the highest (= 0).

Water potential of any solution = negative.

Greater the concentration of a solution, more negative is the water potential.

Water moves from high water potential to low water potential

Water moves from hypotonic solution to hypertonic solution.

The water moves into the bacterial cell by endosmosis.

2. Option B is correct.
