Biology Distance Learning ActivityWednesday 3/25/2020 Unit 3: Cell Transport - Diffusion?Overview:? Students will be able to explain the process of diffusion & facilitated diffusion and its effect on cell homeostasis.Estimated Time:?Approximately 45 minExplanation:?? You should be able to describe how and why diffusion and facilitated diffusion maintain homeostasis in the cell.Materials that are Needed: ALL assignments, links and files will be available in Canvas -> Modules -> distance learningAmoeba Sisters Diffusion Video: Video Recap worksheet: available on canvas->modulesThings to know: About this assignment: This activity will introduce you to the process of Diffusion and Facilitated Diffusion. Diffusion, also known as simple diffusion, is an important process in the maintenance of cellular homeostasis. This process does not require energy. Diffusion can occur across the cell membrane, but only for smaller & non-polar compounds which can pass through the hydrophobic barrier of the cell membrane. For larger or charged particles, the cell may utilize facilitated diffusion. In this process particles will move from high to low concentration, across the cell membrane, with the aid of proteins. These proteins may be channels or carriers. Even though facilitated diffusion utilizes proteins, this is a passive process!Watch the video and complete the worksheet to gain a better understanding of this process. Pause and re-watch sections of the video as needed. The answer key and a short canvas quiz will be posted tomorrow to assess your strengths and weaknesses on this content.Tasks: Download the Amoeba Sisters Recap Video Worksheet – you may complete the worksheet on your laptop or print it out.This is available on Canvas -> Modules -> Distance LearningWatch the video and complete the worksheet. – write your name at the top of your answer sheet. your completed worksheet – make sure that your name at the top of your answer sheet, then submit your answers in one of two ways.Upload the digital copy of your completed answer sheet. -OR_Take a picture of your completed worksheet and upload the images.Submit any questions to me through email. Check back tomorrow to review the answer key and check your understanding.Check your answers to the amoeba sisters recap worksheet using the answer key.This is available on Canvas -> Modules -> Distance Learning. This will NOT be available until your assignment has been marked “complete” by Mrs. Elinow. ................
