Osmosis is Serious Business! Hebrew Translation
Department of Biology
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.
