Eukaryotic cells A. Organelles B. The nucleus 1. nuclear envelope 2. nucleolus 3. chromosomes C. Endoplasmic reticulum and ribosomes D. Golgi bodies E. Lysosomes F. Mitochondria and the endosymbiont theory G. Plant cell components: chloroplasts and cell walls H. The cytoskeleton I. Flagella and cilia

  2. I. The nature of cells Cell (life) requirements

  3. A. Basic cell features 1. plasma membrane = cell membrane = plasmalemma 2. DNA/ RNA/ ribosomes3. cytoplasm

  4. Which of the following is NOT a feature of all living cells? a. ribosomes b. nucleus c. DNA d. cell membrane

  5. Which of the following comes closest to the size of a typical cell? a. 50 nm b. 50 m c. 50 cm d. 50 um

  6. B. Cell theory (well documented, explanatory principle) 1. All living systems are made of cells Inductive reasoning

  7. B. Cell theory 2. All of life’s functions are cellular

  8. B. Cell theory 3. All cells come from pre-existing cells Mitosis and meiosis

  9. Domain Archaea Domain Bacteria III. Prokaryote cells

  10. III. Prokaryote cells calcium

  11. Which of the following is NOT a tenet of the cell theory? a. all living systems are made of cells b. all physiology is cellular c. all cells come from pre-existing cells d. all cells are roughly the same size

  12. What is the basic difference between prokaryotes and eukaryotes? a. prokaryotes are much smaller than eukaryotes b. prokaryotes do not have organelles c. prokaryotes do not have DNA d. prokaryotes have ribosomes; eukaryotes don’t

  13. What type of logic is used predominantly in the cell theory? a. deductive b. inductive c. abductive d. constructive

  14. Domain Eukarya IV. Eukaryote cells A. OrganellesB. The nucleus1. nuclear envelope2. Nucleolus3. ChromosomesC. Endoplasmic reticulum and ribosomesD. Golgi bodiesE. LysosomesF. Mitochondria and the endosymbiont theoryG. Plant cell components: chloroplasts and cell wallsH. The cytoskeletonI. Flagella and cilia Plants Protista Fungi Animals

  15. A. Organelles ‘little organs’ Animal cells

  16. B. The nucleus 1. nuclear envelope2. nucleolus3. chromosomes Histone proteins

  17. C. Endoplasmic reticulum and ribosomes bleb

  18. D. Golgi bodies

  19. E. Lysosomes Tay - Sachs

  20. C6H12O6 + 6O2 6CO2 + 6H2O F. Mitochondria and the endosymbiont theory ATP (Aerobic Respiration) ribosomes enzymes DNA Fission Typhus Living examples

  21. G. The cytoskeleton H. Flagella and cilia

  22. With which of the following organelles does the nucleus work most closely? a. lysosomes b. mitochondria c. rough endoplasmic reticulum d. Golgi bodies

  23. If a man had a disease that prevented the formation of flagella, which one of the following would be a problem for him? a. breathing b. reproducing c. hearing d. moving eggs through his oviducts

  24. We saw evidence that mitochondria evolved from bacteria. What kind of reasoning was involved? a. inductive b. deductive c. intuitive d. circular

  25. I. Plant cells

  26. 6CO2 + 6H2O C6H12O6 + 6O2 I. Plant cells • chloroplast Light Energy (chlorophyll) Photosynthesis: • cell walls-cellulose

  27. Which of the following organelles in NOT found in plants? a. endoplasmic reticula b. mitochondria c. Golgi bodies d. lysosomes

  28. Which of the following organelles does NOT have its own DNA? a. rough endoplasmic reticulum b. mitochondrion c. chloroplast d. nucleus e. more than one of these

  29. The end
