A hypertonic environment has more solute on the outside of the cell. Water moves out of the cell which causes the cell to shrink and crenate.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

An isotonic solution has no net change in water movement because the concentration of solute is the same on both sides of the membrane.

Hypertonic Environment 

Hypotonic solutions have a lower concentration of solute on the inside of the cell. In this environment, water diffuses into the cell which causes it to swell and eventually bursts it.
