Question

which statement describes the movement of water when a cell swells and bursts due to osmosis?
water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
the cell membrane used energy to move water into the cell because there was not enough water inside the cell
the cell membrane used energy to move water out of the cell because there was too much water inside the cell

Explanation:

Osmosis is the passive movement of water across a semi - permeable membrane from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration). When a cell swells and bursts, it means water is entering the cell. This happens because the water concentration inside the cell is lower (so solute concentration is higher) than outside, so water moves in. The third and fourth options are incorrect because osmosis is passive and doesn't require energy. The second option is incorrect as it describes water moving out, which would make the cell shrink, not swell and burst.

Answer:

Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
