Plasma Membrane and Fluid Dynamics
The plasma membrane is an incredibly important part of the cell, and plays a role in nearly all of its functions. This unit takes a close look at the molecular structure of the phospholipid bilayer and how it affects what substances can enter the cell freely, and which cannot. Students will also become familiar with the various mechanisms of fluid transport, including diffusion, osmosis, and active transport.
Plasma Membrane and Fluid Dynamics Lecture Powerpoint
 |
Purpose: The plasma membrane is the boundary that seperates the living cell from its nonliving environment. As such, it must have the ability to control what enters or leaves the cell. This powerpoint covers the basic phospholipid bilayer composition of the membrane, the different types of protein channels, as wel as the carbohydrate markers found on the membrane surface. Students will also learn about the mechanics of diffusion, osmosis, and active transport.
Essential Concepts: Plasma membrane, fluid dynamics, cell membrane, osmosis, diffusion, facilitated diffusion, active transport, hypertonic, hypotonic, isotonic, tonicity, phospholipid bilayer, integral proteins, peripheral proteins, carbohydrate markers, cholesterol, fluid mosaic model, hydrophobic, hydrophilic, phagocytosis, pinocytosis.
Plasma Membrane and Fluid Dynamics Lecture Notes Outline
 |
Purpose: Taking efficient notes can be a big challenge for many students, especially when working from a Powerpoint lecture. This outline gives students a means to take notes that guides them toward important concepts and avoids the pitfalls of writing word-for-word or simply not taking notes at all. The outline is written as a series of questions, fill-in-the-blanks, or diagrams.
Essential Concepts: Plasma membrane, fluid dynamics, cell membrane, osmosis, diffusion, facilitated diffusion, active transport, hypertonic, hypotonic, isotonic, tonicity, phospholipid bilayer, integral proteins, peripheral proteins, carbohydrate markers, cholesterol, fluid mosaic model, hydrophobic, hydrophilic, phagocytosis, pinocytosis.
Investigating Osmosis Effects on Plant Cells Lab
|
Purpose: Plant cells are affected by hypertonic, hypotonic, and isotonic solutions much like animal cells are. However, since plant cells have cell walls, they will not explode like animal cells in hypotonic solutions. This lab has students place carrot sticks in different saltwater solutions. They measure the mass, length, and rigidity of each carrot stick before and after exposure to the solution.
Essential Concepts: Plasma membrane, fluid dynamics, cell wall, osmosis, diffusion, hypertonic, hypotonic, isotonic, tonicity.
Plasma Membrane and Fluid Dynamics Study Guide
|
Purpose: This worksheet is a set of vocabulary words and practice questions meant to encourage students to condense their notes into a more manageable form to study from. The questions and vocabulary are taken directly from the lecture Powerpoint for this unit.
