Get On Task ISN p.85 – answer this: MT 10,11 The Basic Unit of Life! Fri 11/16/12 TOPIC: MY GOAL: Get On Task I will… learn the difference s in several types of microscopes ISN p.85 – answer this: To what part of the Cell Theory did each scientist contribute? Hooke Schleiden Schwann Write the scientists name UNDER one of the 3 parts of Concept Map.. Virchow Janssen Leuwenhoek

Spontaneous Generation This is what they used to think…. Soil + Rain = Frogs Wheat + Corner = Mice Soil + Rain = Worms http://www.youtube.com/watch?v=WNByRghR6sw&safety_mode=true&persist_safety_mode=1&safe=active

All living things are made of cells ISN p.85, Question of the Day What contribution did each scientist make to the Cell Theory? THE CELL THEORY All living things are made of cells All cells come from pre-existing cells Cells are the most basic unit of life Schleiden Hooke Virchow Schwann Janssen Leuwenhoek

Stop Think And Review Why should we care about The Cell Theory? What would happen IF the Cell Theory was never developed? http://www.biotechlearn.org.nz/themes/cell_biology_and_genetics/video_clips/cell_theory_why_is_it_important_v0202 4

The Microscope Your 1st Job Today LABEL scope on ISN p.87 READ in textbook, p.19-21… LABEL scope on ISN p.87 Review & Highlight

The Compound light microscope Please take a few moments and READ Reference page 8 on “Viewing an Object” This should REFRESH your memory as to HOW to CORRECTLY bring something into FOCUS!!

Dissecting scope

Electron microscopes SEM vs TEM Ant Virus Pollen Mitochondria

Types of scopes ISN p.86 Light Microscope Stereo/ Dissecting Microscope SEM = Scanning Electron Microscope TEM = Transmission Electron Microscope Dimension Magnification Can View… Quality of Detail Light Microscope Stereo/ Dissecting Microscope SEM = Scanning Electron Microscope TEM = Transmission Electron Microscope Dimension 2D 3D Magnification 1000X 500X 1000 to 10,000X Scans surface 10,000 to 100,000X Transmits thru Can view Dead… living Dead Most Detail General view Used to dissect larger, thicker structures The Winner!!! smaller; more detail
