Abstract
This directed case study, translated from the original English into Hebrew, involves two “stories,” each concerned with some aspect of osmosis in living cells. Part I is centered around the effects of a hypertonic environment on plant cells, while Part II focuses on the effects of a hypotonic environment on animal cells. After reading the parts, students working in small groups evaluate the information and answer the corresponding questions. This case was designed for use in a non-majors biology course, but could be adapted for use in a majors’ introductory biology course or a high school biology class.
Objectives
- Understand solute concentration and the process of osmosis.
- Be able to determine the net direction of osmosis in a given situation.
- Understand osmosis in plant cells and be able to apply the term plasmolysis.
- Understand osmosis in animal cells and be able to apply the term lysis.
