2	The Advent of the Microscope Anton van Leeuwenhoek (1600s)-first person to use a microscope to identify living things. Robert Hooke (1665)- published a book of drawings of various things seen under a microscope. He was the first to use the word cells to describe the chambers he saw. Robert Brown-discovered an object near the center of the cell that we now call the nucleus.
3	Modern Microscopes Compound Light Microscope- used most commonly in lab settings. Can magnify up to 1000 times.
4	Electron Microscopes Discovered in the 1920s. Objects must be placed in a vacum Can magnify up to 1000 times more than a light microscope. Transmission Electron Microscope (TEM)- shines a beam of electrons through an object.
5	Microscopes Scanning Electron Microscope (SEM)- Uses a beam of electrons to scan the surface of an object. Scanning Tunneling Microscope- Invented in the 1980s. Use a probe to scan the surface of an object. Can be used with living things.
6	The Cell Theory Matthias Schleiden, Robert Virchow, and Robert Brown all contributed to the formation of the cell theory, which states: 1. All living things are composed of cells. 2. Cells are the smallest working units of living things. 3. All cells come from preexisting cells by cell division.
7	Cell Membrane The purpose is to separate and protect the cell from its surroundings. It is made up of a lipid bilayer. It also has carbohydrate chains, and membrane proteins found throughout the membrane.
8	Inside the Cell Nucleus What is the purpose of the nucleus? What are the parts of the nucleus? What is everything found outside the nucleus found in?
9	Inside the Cell Ribosomes What is their purpose in the cell?
10	Inside the Cell Endoplasmic Reticulum Two types: Smooth and Rough What is their function?
11	Inside the Cell Golgi Apparatus What is the function of this organelle?
12	Inside the Cell Lysosomes What is their function in the cell?
13	Inside the Cell Vacuoles Types of Vacuoles found in the cell. Food Contractile Central What is their function in the cell?
14	Inside the Cell Mitochondria What is the function of this organelle? What types of cells would you find many mitochondria? Found in BOTH animal and plant cells.
15	Inside the Cell Chloroplast What kind of cells is this organelle found in? What is the function of this organelle?
16	Types of Cells Which is which?
17	Types of Transport Passive Transport Diffusion-Movement of substances from high to low concentration. Osmosis-Movement of water from high to low concentration. Facilitated Diffusion- Movement of substances thorough the use of protein channels. Active Transport Sodium Potassium Pump Endocytosis Exocytosis Where are they found?
18	Types of Transport
19	The Circulatory System Functions of the Circulatory System The Heart Blood Vessels Blood Pressure Blood Blood Types The Lymphatic System
