Presentation Transcript

  1. Week 5 1. Which of the following elements are always present in carbohydrates, proteins, nucleic acids, and lipids? • Carbon, nitrogen, and sulfur • Carbon, hydrogen, and oxygen • Carbon, nitrogen, and oxygen • Nitrogen, hydrogen, and oxygen

  2. 2. What cell structures would indicate that you are examining a plant cell rather than an animal cell? • Nucleus and chloroplasts • Cell wall and chloroplasts • Chloroplasts and mitochondria • Chromosomes and vacuoles

  3. 3. How does a eukaryotic organism differ from a prokaryotic organism? • A prokaryotic organism is not made up of cells. • A prokaryotic organism does not contain genetic information. • A eukaryotic organism has many cells, and a prokaryotic organism has only one. • The cells of a prokaryotic organism do not have nuclei.

  4. 4. What evidence indicated that the cell must be a plant cell? • The well-defined nucleus and ribosomes • The presence of a cell membrane and cytoplasm • The water-filled vacuole, chloroplasts, and cell wall • The fact that is it only one cell (unicellular)

  5. 5. Energy is gained in an ADP molecule when which of the following occurs? • ADP loses and electron • ADP binds to a ribose • ADP gains a phosphate group • ADP gains a nucleotide.

  6. 6. In cells, large structure inside some cells that contain the cell's genetic material (DNA) and controls the cell's activities is the _________________. • Ribosome • Lysosome • Golgi apparatus • nucleus

  7. 7. This organelle packages, sorts, and delivers proteins • Lysosome • ER • Mitochondria • Golgi bodies

  8. 8. The endoplasmic reticulum • Transport materials • Destroy old cell parts • Make ribosomes • Control what enters and leaves the cell.

  9. 9. Located within the nucleus, it is responsible for producing ribosomes • Centrosome • Nucleolus • Lysosome • Endoplasmic reticulum

  10. 10. Which structure is directly responsible for the formation of proteins within the cell? • Lysosomes • Vacuoles • Centrioles • Ribosomes
