BIOLOGY BELL RINGERIAN PG. 68 Week of 11/16/2015 Thursday 11/19/15 After completing the lab Mr. D asks you to clean up your lab bench and properly store your microscope. You have a slide on the stage and your microscope is on high power. Explain the proper procedure for storing your microscope.

7-1 LIFE IS CELLULAR MAIN IDEAS 1.Cell 2.Cell Theory 3.Nucleus 4.Eukaryote 5.Prokaryote Objective Explain cell theory describing microscopy to differentiate Prokaryotes & Eukaryotes. IAN PG. 77 Key Concepts: 1. What is the cell theory? 2. What are the characteristics of prokaryotes and eukaryotes?

7.1 LIFE IS CELLULAR IaN pg. 77

A. The Discovery of the Cell ’s Robert Hooke & Anton Van Leeuwenhoek first to use microscopes to observe cells a. Hooke discovered cells while examining cork tissue using compound light microscope. Came up with term “cell” because they resembled tiny rooms

b. Leeuwenhoek first to look at living cells in pond water

Microscopes Compound light SEM – Scanning Electron Microscope TEM – Transmission Electron Microscope

The Cell Theory

All plants are made of cells Matthias Schleiden

All cells come from other living cells Virchow

The Cell Theory All living things are composed of cells. Cells are the basic unit of structure and function in living things. New cells are produced from existing cells.

All cells have: – Cell membrane – Cytoplasm – Genetic material (DNA) Cells
