Electron Microscopes
1940’s – uses a beam of electrons instead of natural light to magnify structures up to 500,000x Scanning Electron Microscopes (SEM)
- scans surface of cells to learn 3D shape Transmission Electron Microscope
(TEM) - study the structures contained in the cell
Scanning Tunneling Microscope (STM) – uses flow of electrons to investigate atoms on the surface of the molecule

2 Basic Cell Types1. Prokaryotes – Cells that do not have an internal membrane bound structure – unicellular like bacteria2. Eukaryotes – cells containing membrane bound structures multicellular like algae, yeastOrganelles – small membrane bound structures allows various chemical reactions to occur simultaneouslyBrown, Virchov – decided main structure that was responsible for cell divisionNucleus – central membrane bound organelle that manages cellular functions

Structure of Plasma Membrane
Phospholipids – lipids with a phosphate group attached to themPlasma membrane has a glycerol backbone, 2 fatty acid chains and a phosphate group
![Page 24: December 6, 2010 Beginning with van Leeuwenhoek Create a time line with the names of those instrumental in discoveries connected with the microscope and](https://reader030.vdocuments.us/reader030/viewer/2022012916/56649e745503460f94b74eb9/html5/thumbnails/24.jpg)
Fluid Mosaic model
Model of the plasma membrane where molecules are free to move sideways within a lipid bi-layerPolar head outside attracts water but is selectively permeable

Cell Membrane
![Page 29: December 6, 2010 Beginning with van Leeuwenhoek Create a time line with the names of those instrumental in discoveries connected with the microscope and](https://reader030.vdocuments.us/reader030/viewer/2022012916/56649e745503460f94b74eb9/html5/thumbnails/29.jpg)
Diffusion Lab
Every cell is covered by a membrane that controls what can enter and leave the cell. The cell membrane or plasma membrane is selectively permeable. It allows some substances to enter and keeps some substances out. This is important for all life processes. A diagram of cell membrane structure is below.
![Page 30: December 6, 2010 Beginning with van Leeuwenhoek Create a time line with the names of those instrumental in discoveries connected with the microscope and](https://reader030.vdocuments.us/reader030/viewer/2022012916/56649e745503460f94b74eb9/html5/thumbnails/30.jpg)
Diffusion Lab (cont)The cell membrane is made up of lipids and proteins. Small non-polar molecules can go right through the membrane by osmosis but ions or larger molecules need assistance by either diffusion and/or by transport proteins.
