Question

What are isotonic and hypertonic solutions?​

Answer 1

Explanation:

What are hypertonic solutions?

Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.

what are isotonic solutions

Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.

Answer 2

Isotonic solutions:

• Isotonic solutions are those which have the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.

• The isotonic solution allows the cells to move the nutrients in and out of the cells. This is necessary for blood cells to perform their function of delivering oxygen and other nutrients to other parts of the body.

• Examples: Blood cells, osmoconformers, and osmoregulatory.

Hypertonic solution:

• Hypertonic solutions are those which have is one that has a higher solute concentration outside the cell than inside. If a cell is placed here, the cell will lose water and shrink. Thus water molecules move from inside to outside the cell.

• For example, plant cells use a hypertonic solution within their central vacuole to help draw water into the vacuole. This expands the chamber and allows plants to create turgor pressure in their cells.
• The electrical activity of these cells relies on the positive and negative charges of the ions in hypertonic solution.

• Example: Human kidney, sea turtle osmoregulation.
