Unit 2 Info Be aware of support structures in cytoskeleton Microtubules Act as transport feature as well Easily broken down and reformed Microfilaments: Circulation of cytoplasm Intermedia filaments support for cytoskeleton Any shape change involves cytoskeleton All three assist in the change in shape Water potential Depends on solute concentration and pressure Presence of solutes makes water potential lower Pressure can set the potential to zero evening everything out Hypotonic Hypertonic Cis receives the contents in the Golgi Trans transports the contents in the Golgi Rough ER has ribosomes so they construct proteins Smooth ER is making complex carbs and lipids Hormones are made of lipids

Endomembrane System This system controls the process of making proteins specified by the DNA in the nucleus and includes the organelles of the smooth ER, rough ER, and golgi apparatus. *Although ribosomes make proteins, it is not included in this system because it is not a membrane bound organelle and just composed of RNA and proteins.

Ch 6: A Tour of the Cell Concept 6.2: Eukaryotic cells have internal membranes that compartmentalize their functions The basic structural and functional unit of every organism is one of two types of cells: prokaryotic or eukaryotic Only organisms of the domains Bacteria and Archaea consist of prokaryotic cells Protists, fungi, animals, and plants all consist of eukaryotic cells Overview: The Fundamental Units of Life All organisms are made of cells The cell is the simplest collection of matter that can be alive Cell structure is correlated to cellular function All cells are related by their descent from earlier cells Comparing Prokaryotic and Eukaryotic Cells Basic features of all cells: Plasma membrane Semifluid substance called cytosol Chromosomes (carry genes)

AP Biology Reading Guide Chapter 6: A Tour of the Cell Fred and Theresa Holtzclaw Copyright ? 2010 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 6: A Tour of the Cell Concept 6.1 To study cells, biologists use microscopes and the tools of biochemistry 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses; and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference.

Name_________________________________Date_______________________Pd._____ Cell Review Worksheet Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once. Structure/Function Cell part 1. Stores material within the cell 2. Digests excess or worn-out cell parts, food particles and invading viruses or bacteria 3. Site of protein synthesis 4. Jelly-like substance in the cell 5. Organelle that manages or controls all the cell functions in a eukaryotic cell 6. Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color

Cells Use molecules to: Transform energy and matter Respond to the environment Reproduce themselves Lowest level that can perform all activities required for life Cell theory Cells are the fundamental units of life All organisms are composed of cells All cells are going to be derived from preexisting cells Are similar in chemical composition Concept 6.1 Microscopes and the Tools of Biochemistry are used to Study Cells Magnification: ratio of image size to real size Resolution: measure of clarity What is the minimum distance required to distinguish two points as separate Light microscopy View living cells Magnify 2000X Resolution: 200nm Electron microscopes View dead cells Magnify 2,000,000X Resolution 0.2 nm Scanning electron microscopy Surface of a specimen (3D)

Mica Piro Chapter 6: A Tour of the Cell Biologists Use Microscopes and the Tools of Biochemistry to Study Cells (6.1) Microscopy Microscopes first used by Renaissance scientists are all light microscopes (LM) Visible light passed through the specimen and then through glass lenses Lenses refract/bend the light so the image of the specimen is magnified as it is projected into the eye or into a camera Magnification: ratio of an object?s image size to its real size LMs can magnify about 1,000 times the actual size Higher magnification = less detailed image Resolution: a measure of the clarity of the image?minimum distance 2 points can be separated and still be distinguished as separate points Contrast: the difference in brightness between the light and dark areas of an image
