Chapter 7 The Cell I. A Panoramic View a. Prokaryote vs. Eukaryote (differences) i. Size ii. Complexity iii. Location of genetic material 1. prokaryotes have chromosome concentrated in NUCLEOID region of the cell 2. eukaryotes have MEMBRANE-BOUND NUCLEUS b. ALL CELLS have i. Cytosol (fluid where organelles are found) 1. Cytoplasm = cytosol PLUS organelles ii. Chromosomes iii. Ribosomes iv. Plasma membrane II. Eukaryotic Cells a. Animal Cell i. Plasma membrane ii. microvilli 1. projections of the membrane a. function to increase surface area iii. Nucleus (stores genetic information) 1. nuclear envelope 2. nucleolus 3. chromatin (chromosomes + protein) iv. Centrosome 1. pair of centrioles found next to the nucleus 2. site of microtubule initiation v. Endoplasmic Reticulum (functions in membrane synthesis, “proteins-for-export” synthesis, detoxification) 1. smooth 2. rough vi. Golgi 1. site of synthesis, sorting and secretion vii. Flagellum (locomotion) 1. composed of microtubules viii. Lysosome 1. “waste dump” ix. Peroxisome 1. specialized lysosome: produces hydrogen peroxide as it degrades waste x. Mitochondrion 1. site of cellular respiration

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
