Question

solutions, consider how water moves when a cell is placed in three types of three types of solutions hypotonic solution hypertonic solution isotonic solution solute h₂o h₂o h₂o h₂o h₂o h₂o h₂o h₂o h₂o net water gain, cell swells net water loss, cell shrinks no net loss or gain type of solution example effect hypotonic a red blood cell is placed in a solution that has more water (or greater solvent concentration) outside the cell than inside the cell. water flows into the cell. the cell swells and possibly bursts. hypertonic a red blood cell is placed in a solution that has less water (or lower solvent concentration) outside the cell than inside the cell. water flows out of the cell. the cell shrinks. isotonic a red blood cell is placed in a liquid with an equal amount of water outside the cell and inside the cell. there is no net movement of water. this is osmotic balance. your turn 3. write one of the three types of solutions next to its description or example. description solution type a. your cells are in osmotic balance and, thus, do not shrink or swell. b. this is why the liquid portion of your blood is not pure water. c. this is why few organisms live in the highly salty dead sea.

Explanation:

a. Osmotic balance with no cell - shrinkage or swelling occurs in isotonic solutions.
b. The liquid portion of blood is not pure water to maintain an environment that is not overly hypotonic or hypertonic for cells, which relates to the concept of isotonicity to keep cells stable.
c. The highly salty Dead Sea is a hypertonic environment for most organisms, causing water to flow out of their cells and making it difficult for them to survive.

Answer:

a. Isotonic
b. Isotonic
c. Hypertonic
