1. Cells & Scopes, Baby! Ch 4 Youre made of them so dont you thinkyou need to know allllllll about them!Learn it, or else Illfind you and then Illuse yourimagination! Wahahahaha! Checkout this video!http://www.xtranormal.com/watch/7316011/

2. AP BioCh 4 A Tour of the CellGoals Describe the difference between the light microscope, transmission electron microscope & scanning electron microscope. List one benefit of using the light microscope over either of the two electron microscopes. State what part of a cell can be viewed by a TEM & SEM. Distinguish between prokaryotic & eukaryotic cells. Explain why cells cant be too large or too small. Explain the importance of compartmentalization in eukaryotic cells. Describe the structure & function of the following cellular parts: Cytoplasm (aka cytosol), cell membrane (aka plasma membrane), nucleus, nucleolus, nuclear envelope, chromatin & chromosome, ribosome, endoplasmic reticulum (smooth & rough), transport vesicles, Golgi bodies, vacuoles, peroxisome, mitochondria, chloroplast, cytoskeleton, centrioles, flagella & cilia, cell wall, extracellular matrix, plasmodesmata, gap junctions, tight junctions. Describe & identify the parts of a mitochondria & chloroplast. Be able to label a plant & animal cell with the above parts. 3. Transmission electronmicroscope 4. Scanning Electron Microscope 5. Caption: HIV infection. Budding release of HIV in human lymph tissue (RNAvirus, Retroviridae Family).Magnification*: x27,630Type: TEM 6. sem 7. (Danaus plexippus). Alsovisible is the last tarsalsegment with thicksetae. Insect claws areused to hold on to roughsurfaces such as leavesand flowers. 8. http://www5.pbrc.hawaii.edu/microangela/morebugs.htmLink to insect images taken w/ SEM 9. Onion Epidermis (clm) 10. Elodea under 40x, 100x, 400x (clm) 11. Human cheek cells 400x (clm) 12. Benefits of light scope over electron vice versa Light living specimens, lower mag Electron deadspecimens, artifacts, higher mag 13. Cells Basic unit of life Mostly water Made of largemolecules(carbohydrates, proteins, fats, nucleic acids) Think of them as littlechemical factoriesthat work together tokeep us alive. http://www.youtube.com/watch?v=BVvvx5HGpLg 14. I lovecells! 15. Cell Fractionation 16. Cell Sizehttp://www.cellsalive.com/howbig.htm 17. 2 Basic Cell TypesProkaryotes Eukaryotes 18. Prokaryotes No organelles (membrane bound compartments) All bacteria 19. Prokaryotes Containthefollowing: Cell wall Cellmembrane DNA Ribosomes cytoplasm 20. Contain organellesEukaryotes(membrane boundcompartments) All cells that arentbacteria More efficient thanprokaryotes sincecompartmentalized. Much larger thanprokaryotes http://www.youtube.com/watch?v=Jn9oJtXZYcU&feature=pyv&ad=3444868461&kw=cell&gclid=CNK7yY_Jyp0CFc5L5QodGWP4rg 21. Cell Part Functions Cell Membrane - formsthe outer boundary of thecell and allows onlycertain materials to moveinto or out of the cell Cytoplasm - a gel-likematerial inside the cell; itcontains water andnutrients for the cell Nucleus - directs theactivity of a cell; itcontains chromosomeswith the DNA Nuclear Membrane -separates the nucleusfrom the cytoplasm 22. Cell Part Functions EndoplasmicReticulum - movesmaterials around inthe cell Ribosomes - makeprotein for the cell Golgi Bodies - areused for packagingand secreting ofchemicals Mitochondria - breakdown food andrelease energy tothe cell 23. Cell Part Functions Lysosomes - arechemicals used todigest waste Vacuoles - are storageareas for the cell Some organelles arefound only in Plantcells. These organellesare: Cell Wall - providesstructure to the plantcell Chloroplasts site ofphotosynthesis (makingsugar from sunsenergy) 24. Cell Part Functions Peroxisomes membound sacs.Contain peroxidase Centrioles functionin cell division 25. Eukaryotes
