Chapter 3 Section 2, The Cell Essential Question: What are the 2 characteristics shared by all cells? Key Words
 * SPECIALIZED CELLS
 * CELL MEMBRANE
 * DNA
 * ORGANELLES
 * NUCLEUS
 * CHROMOSOMES
 * NUCLEAR MEMBRANE
 * CYTOPLASM
 * VACUOLES
 * RIBOSOMES
 * ENDOPLASMIC RETICULUM
 * GOLGI BODY
 * MITOCHONDRIA
 * LYSOSOMES

Specialized Cell Cell Structures
 * 1) Cells come in many shapes and sizes.
 * The eggs of a chicken are examples of cells you can see with your eye, while bacteria are single celled organisims that can only be seen with the aid of a microscope.
 * 1) Multicellular organisims have many different types of cells. Each type has a different purpose or function.
 * All cells in an organisim have the same DNA. This allows a cell to be any type of cell.
 * Cells differentiate themselves from other cells.
 * Muscle, Nerve, Skin, Blood etc....
 * Cells that perform a specific function are called SPECIALIZED CELLS.
 * 1) Specialized Cells that group togather is called tissue
 * 1) Not all cells have the same structures, but all cells have two things in common
 * Cell Membrane
 * DNA
 * 1) Organelles
 * cell parts that have specific functions but work with other organelles. Like our organs work togather to make a system
 * 1) Nucleus
 * Discovered in 1831 by Robert Brown
 * Control center of the cell
 * Controls activities of cell and stores the instructions for making proteins
 * 1) Chromosomes
 * Long threads of DNA that contain all information needed to make a complete organisim
 * 1) Nuclear Membrane
 * Gate around White House
 * Seperates the Nucleus from the rest of the cell
 * 1) Cytoplasm
 * Jelly like substance where all the cell activities take place
 * 1) Cell Membrane
 * Border Patrol
 * Surrounds the cytoplasm holding it in place, while controlling what goes in and out of the cell
 * 1) Vacuoles
 * Grocery stores
 * Storage cites of the cell.
 * Store food, water, minerals, and waste
 * 1) Ribosomes
 * Factories of the Cell
 * Produce proteins
 * 1) Endoplasmic Reticulum (ER)
 * Highway of the cell
 * Connects Nuclear Membrane with the rest of the cell
 * Moves material throughout the cell
 * 1) Golgi Bodies
 * Shipping and packaging department of the ribosomes
 * package proteins and with help of ER ships proteins to other parts of cell or outside of the cell
 * 1) Mitochondria
 * Duke Power
 * Work with Lysosomes to produce the energy the cell needs to grow, work, and reproduce
 * 1) Lysosomes
 * Recycling Plant
 * Recycle worn or unneeded materials
 * Help body break down nutrients absorbed by cell to convert to energy
 * Help bread down bacteria in your body
