Questions and Answers

What occurs when a cell is placed in a hypertonic solution?

The cell membrane becomes impermeable

Water moves out of the cell, causing it to shrink (correct)

The cell remains the same size

Water moves into the cell, causing it to swell

What type of solution has a solute concentration equal to that inside the cell?

Isotonic (correct)

Hypertonic

Hypotonic

Osmotic

What happens to a cell when it is placed in a hypotonic solution?

It remains the same size

It shrinks due to water loss

It becomes impermeable to water

It swells or bursts due to water gain (correct)

Study Notes

Solutions and Their Effects on Cells

Hypertonic Solution: A solution with a higher concentration of solutes outside the cell, leading to water moving out of the cell through osmosis, resulting in possible cell shrinkage.
Hypotonic Solution: A solution with a lower concentration of solutes outside the cell, causing water to move into the cell through osmosis, which can lead to cell swelling or even bursting.
Isotonic Solution: A solution where the solute concentration is equal inside and outside the cell, resulting in no net water movement, and the cell size remains constant.
