  1. A Tour of the Cell 0 4 Questions prepared by Brad Stith,University of Colorado Denver Jung Choi,Georgia Institute of Technology

  2. Which cellular structure is common to all three domains of life? • nucleus • endoplasmic reticulum • mitochondria • phospholipid bilayer cell membrane • endocytotic vesicles

  3. Which cellular structure is common to all three domains of life? nucleus endoplasmic reticulum mitochondria phospholipid bilayer cell membrane endocytotic vesicles

  4. Enzymes responsible for biosynthesis of membrane lipids would be located in what part of the cell? endoplasmic reticulum nucleus lysosomes Golgi plasma membrane

  5. Enzymes responsible for biosynthesis of membrane lipids would be located in what part of the cell? endoplasmic reticulum nucleus lysosomes Golgi plasma membrane

  6. Which of the following is not an argument for the theory that mitochondria and chloroplasts evolved from prokaryotic endosymbionts? Mitochondria and chloroplasts have double membranes. Mitochondria and chloroplasts have their own ribosomes. Mitochondria and chloroplasts have their own DNA. The mitochondrial and chloroplast genomes are circular. All of the above support the endosymbiotic theory.
