1. The ideal osmotic environment for an animal cell is a(n) environment. 2. An animal cell placed in a(n) solution will gain water, swell, and possibly burst. 3. There is a net diffusion of water out of an animal cell when it is placed in a(n) solution. 4. The ideal osmotic environment for a plant cell is a(n) environment. 5. A plant cell placed in a(n) solution will lose water and plasmolyze. 6. A plant cell surrounded by a(n) solution will be flaccid (limp).

The ideal osmotic environment for an animal cell is an isotonic environment. That is, an environment with a solution that has the same solute concentration as the cytosol.

An animal placed in a hypotonic solution will gain water, swell, and possibly burst because there is a net movement of water from the solution to the cytosol due to the osmotic gradient. A hypotonic solution is one with a lower solute concentration than that of the cytosol.

When an animal cell is placed in a hypertonic solution, a solution that has more solute concentration than the cytosol, there is net diffusion of water out of the cell into the surrounding solution.

The ideal osmotic environment for plant cells is a hypotonic environment. That is, an environment with lower solute concentration compared to the cytosol. A plant cell placed in a hypertonic solution would lose water and become plasmolyzed. In an isotonic solution, a plant cell would become flaccid because there would be a lack of turgor pressure as a result of inadequate water in the cells.
