Question

label the tonicity for each solution (isotonic, hypotonic, or hypertonic):

Explanation:

Isotonic solutions have equal solute - solvent concentration inside and outside the cell, so no net water movement. Hypotonic solutions have lower solute concentration outside the cell, causing water to move into the cell. Hypertonic solutions have higher solute concentration outside the cell, causing water to move out of the cell. Based on the appearance of the cells and water movement arrows in the images:

1. First row, first cell: Appears normal, no net water movement, isotonic.
2. First row, second cell: Swollen, water moving in, hypotonic.
3. First row, third cell: Shriveled, water moving out, hypertonic.
4. Second row, first cell: Appears normal, isotonic.
5. Second row, second cell: Swollen, hypotonic.
6. Second row, third cell: Shriveled, hypertonic.

Answer:

1. Isotonic
2. Hypotonic
3. Hypertonic
4. Isotonic
5. Hypotonic
6. Hypertonic
