20. A cell placed in pure water has swelled. Why?
  1. The cell was in an isotonic environment, so water flowed into it.
  2. The cell was in a hypotonic environment, so water flowed into it.
  3. The cell was in a hypertonic environment, so water flowed into it.
  4. The cell was in a hypotonic environment, so water flowed out of it.
  5. The cell was in a hypertonic environment, so water flowed out of it.
