Explanation / Answer

Answer 1(a): In a hypotonic solution, animal cell brust. In red blood cells, this is called hemolysis or endosmosis. In a hypertonic solution, animal cells shrink. In red blood cells this is called crenation or exosmosis.

Explanation - If an animal cell was placed in a hypertonic solution, the cell shrinks, because it loses water (water moves from a higher concentration inside the cell to a lower concentration outside) and when an animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

1(b) In a hypotonic solution,the central vacuole of Elodea cells exerts turgor pressure, and chloroplasts are seen next to the cell wall. In a hypertonic solution, the central vacuole loses water and plasmolysis occurs. The cytoplasm plus the chloroplast are seen in the middle of the cell.

Explanation - In a hypotonic solution, the central vacuole of Elodea cells exerts a force within the cell that pushes the plasma membrane and chloroplasts are seen next to its cell wall, and if the central vacuole was placed in hypertonic solution then it loses water and plasmolysis might have occurred. The cytoplasm plus the chloroplast would be seen in the middle of the cell.

1(c) In a hypotonic solution, potato strips gains water and become stiff potato strips; In a hypertonic solution, potato strips losses water and become limp.

Explanation - When potato strip was placed in a hypotonic solution, then water diffused into potato strip and makes potato strip stiff. Similarly, In salt solution or hypertonic water diffused out from the potato strip and makes potato strip limp.
