Question

solution a, we would expect no change in the cells, because solution a is ____________ to the cytoplasm of each cell.

1. let’s put both cells into solution b. because solution b is hypertonic to the cytoplasms of the cells, we would expect water to __________ the cells through the process of __________. this would result in the cytoplasm of both cells shrinking.
2. now we’ll put both the plant and animal cell into solution c, which, because it contains no solutes at all, is __________________ to the cytoplasm of both cells. ________________ will enter both cells through osmosis. the animal cell is likely to ________, unfortunately. the plant cell, however, is protected from this because of the presence of its __________.

Explanation:

1. When there is no change in cells, the solution is isotonic to the cytoplasm as the solute - solvent balance is equal.
2. In a hypertonic solution, water leaves the cells through osmosis due to the higher solute concentration outside.
3. A solution with no solutes is hypotonic. Water enters cells by osmosis. Animal cells may burst as they lack a cell wall, while plant cells are protected by their cell walls.

Answer:

1. isotonic
2. leave; osmosis
3. hypotonic; Water; burst; cell wall
