The Parts of the Cell The Nucleus --nuclear envelope -- chromatin --nucleolus
I am a reticulated python. Ask me what I have to do with the endoplasmic reticulum. Endoplasmic Reticulum - Transport Golgi Apparatus - delivery system Cis Face | Trans Face
Cisternae (folds) Vesicles - package to be delivered Ribosomes - Sites of Protein Synthesis large subunit
small subunit Each ribosome has a large and small subunit Messenger RNA is threaded through the ribosomes Transfer RNA builds a protein based on the code of the mRNA
Lysosomes - Intracellular Digestion Centers TAY-SACHS disease What do lysosomes have to do with this deadly disease? Other Organelles -- Peroxisomes result in hydrogen peroxide, broken down
by catalase -- Vacuole -- mainly storage or specific functions (contractile vacuole) -- Plant cells have a CENTRAL VACUOLE - used for storage and help to maintain hydrostatic pressure Energy Related Organelles
Mitochondria - The Cell's Chemical Furnaces, produces ATP Chloroplasts - Where Photosynthesis Takes Place What do these organelles have in common? What happens if your mitochondria dont work? Mitochondrial Disease Video
Why is mitochondrial disease so devastating to children? Consider the mitochondria have their own DNA separate from the parental DNA. How could you cure this disease?
Cytoskeleton How do cells maintain their shape? Microfilaments (actin filaments) Microtubules - form the spindle during cell division Centrioles used during cell division to move and separate chromosomes, only found in animal cell
How do they move? - pseudopod - cilia - flagella The Big Picture Mini Quiz

Can you describe this process in 10 words or less? Figure 4.7b Show, Don't Tell
Each person will get a cell concept . For your concept, design a picture that goes with it and a GESTURE for the idea. Be prepared to share your pictures and gestures with the class. Your classmates will use your picture and your gesture to guess what your concept was. Its like playing a twisted form of charades! You should be
able to draw your picture on the fly, on the board, but have a plan in place before you go up there. Terms / Concepts for Show, Don't Tell cell_theory mitochondria chloroplast
This is a rapid change in polarity across the axomembrane. Broken into an upswing and downswing: 1. During upswing . Sodium gates open & Na+ flows into the axon. This causes depolarization going from negative to positive (-65 mV to...
