Corresponds with Chapter 5 Openstax Biology 2e "Structure and Function of Plasma Membrane"
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Explain why and how passive transport occursUnderstand the processes of osmosis and diffusionDefine tonicity and describe its relevance to passive transport
Worksheet that goes over the types of transport associated with a cell membrane.
Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. They view online animations of cell membrane dynamics (links provided). Then they observe three teacher demonstrations that illustrate diffusion and osmosis concepts, as well as the effect of movement through a semi-permeable membrane using Lugol's solution.
This is an illustration of environmental tonicity conditions for animal cells and plant cells. The response of red blood cells and platn cells to hypertonic, isotonic, and hypotonic conditions is indicated.
