Question 18 2 pts 2 pts 2 013 Which of the following statements correctly describes the normal tonicity conditions for typical plant and animal cells? The animal cell is in a hypotonic solution, and the plant cell is in an Isotonic solution The animal cell is in an isotonic solution, and the plant cell is in a hypertonic solution The animal cell is in a hypertonic solution, and the plant cellis in an isotonic solution The animal cell is in an isotonic solution, and the plant cell is in a hypotonic solution The animal cell is in a hypertonic solution, and the plant cell is in a hypotonic solution

Answer 1

In this case, remember that plants requires water in order to maintain theirs structure and remain swell. For this, it is required a solution with less concentration of water than the inside of the cell. The water will move by osmosis to the cell, maintaining its rigid structure. So, the cell must be in a hypotonic solution.

On the other hands, animal cells are a little more complex. The requires water but not in excess since they do not posses cell wall and they can break. For this, we need a isotonic solution where inside and outside the cell have the same concentration. So, the correct answer is The animal cell is an isotonic solution, and the plant cell is in a hypotonic solution
