The Plasma Membrane = The Cell Membrane The Most Important Job… Maintaining HOMEOSTASIS Homeostasis = internal balance All living cells must maintain.
Diffusion & Osmosis. THE CELL MEMBRANE AND THE FLUID MOSAIC THEORY - explain how food And gases enter and leave the cell Flip flop theory Explains how.
Passive Transport. Healthy Cell 70% water 15% protein 10% fat 4% DNA and other materials 1% carbohydrate.
Diffusion & Osmosis. Define Diffusion The movement of molecules from a area in which they are highly concentrated to a area in which they are less concentrated.
Transport through the Cell Membrane. Passive Transport Movement across a cell membrane that does not require energy 2 examples: Diffusion Osmosis.
1. How many factors are involved in transporting the goods shown from the manufacturer to a store? 2. What might happen if one of the factors is temporarily.
1 Unit 5 Cell Structure & Transport. 2 Cell Theory All living things are composed of cells Cells are the basic unit of structure and function in living.
Label the following parts of the cell: B A. Lophotrichous Flagella Cell Membrane.
Transport: Passive and Active. Structure of Cell membranes Fluid not rigid Selectively permeable Made of a phospholipid bilayer Embedded with proteins.
Cell Transport and Division Rebecca Maloney, Ciara O’Shea, Madeleine Skipworth, Will Rips, Jonathan Wakeman Period 1.
OSMOSIS and DIFFUSION. Exchange with the Environment Organisms are able to obtain energy and raw materials and get rid of waste Why would that be important???
Cell Membrane & Passive Transport Diffusion Facilitated Diffusion Osmosis.
