Maintaining a Balance. 1.The plasma membrane is a SELECTIVELY (SEMI-) PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell.
Chapter 5 Cell Membrane. Plasma Membrane --the fluid mosaic model (S.J Singer) -- semi-permeable --fluid portion is a double layer of phospholipids, called.
Transport-cell membrane Do Now : What is homeostasis? What is transport? Brainstorm : Can you brainstorm one way that transport helps to maintain homeostasis.
T HE P LASMA M EMBRANE. O NLY 2 MOLECULES THICK, THIS MEMBRANE ALLOWS THE PASSAGE OF ESSENTIAL MOLECULES IN AND OUT OF THE CELL.
Cells and Their Environment Chp 4. I. Cell Membrane a.Cell membrane also known as plasma membrane, selectively permeable membrane, and semi-permeable.
Scanning Electron-looks at a samples surface Transmission Electron-can look at internal structures Remember….these two can only be used to look at.
The Structure of the Cell Membrane
The Cell – Label me! 1. Learning Objectives 1.Describe the fluid mosaic model of membrane structure and explain the underlying reasons for this structure.
