Question

1. which type of cells thrive in an isotonic solution?

plant cells
cells with a cell wall
animal cells
both plant and animal cells

Explanation:

In an isotonic solution, the concentration of solutes is the same inside and outside the cell. Animal cells lack a cell wall. In a hypertonic solution, they would lose water and shrink (crenation), and in a hypotonic solution, they would gain too much water and burst (lysis). But in an isotonic solution, water moves in and out at an equal rate, so animal cells maintain their normal shape and function. Plant cells (which have a cell wall) can also survive in isotonic solutions, but they thrive (get turgid - the ideal state for plant cells) in a hypotonic solution (where water enters the cell and pushes against the cell wall). So the key is that the question is about which type "thrive" in isotonic. Animal cells do well (maintain normalcy), plant cells with cell walls prefer hypotonic for turgidity.

Answer:

C. animal cells
