What does it mean for an environment to be isotonic?

Question

1. The concentration of solute is greater in the environment inside the cell.
2.The concentration of solute in the environment is different from the concentration inside the cell.
3. The concentration of solute is greater inside the cell than the environment.
4. The concentration of solute in the environment and inside the cell are at an equilibrium.
Thank you very much!

Answer 1

An isotonic environment refers to a situation where the concentration of solute inside the cell is equal to the concentration of solute in the surrounding environment. Therefore, the correct option is:

4. The concentration of solute in the environment and inside the cell are at an equilibrium.

In an isotonic solution, there is no net movement of water into or out of the cell, which helps maintain cell shape and function.
