Cells Unit Test Review Prokaryote Nucleus Membrane Bound Organelles Ribosomes DNA Reproduce/Replicate Cell Membrane Example Eukaryote X Virus X X X X X Bacteria X X X X X/W CELL X Plant/Animal/Protist/Fungi Influenza 1. Prokaryotes DO NOT have: Nucleus or membrane bound organelles 2. If a cell has a nucleus it is a: Eukaryote 3. Viruses are non living but are exceptions to the cell theory because they have: They contain genetic material (nucleic acid) 4. How do you prevent the spread of a virus? Vaccination 5. Define organelle? Structure within a cell that performs a specific function 6. Levels of organization – where to organelles fit? Atom-element-molecule- organelle - cell-tissue-organ-organ systemorganism-species-population-community- ecosystem- biosphere 7. Why is bacteria classified as living and viruses classified as non living? Bacteria can reproduce on their own and viruses cannot – bacteria uses binary fission and viruses uses lytic and lysogenic cycle 8. Compare the size of eukaryotic and prokaryotic cells? Eukaryotic cells are larger than prokaryotic 9. What is influenza to a virus? Influenza is a disease caused by a virus 10. Why are viruses characterized as nonliving particles? Don’t have a metabolism 11. How is the lysogenic cycle different for the lytic cycle? The host cell isn’t destroyed immediately 12. What are the steps of viral replication? Attach to cell – Injection of genetic material – replication of DNA/RNA – Assembly of Proteins – Reproduce viruses – Destroys host cell – cycle repeats 13. What is the monomer of DNA? Nucleic acid 14. The enzyme catalase breaks down hydrogen peroxide into water and oxygen. During this reaction, the catalase IS UNCHANGED 15. How much energy travels through a food pyramid? Who would get 1%? 10% -- Secondary Producer 16. What is a tertiary consumer? Third level consumer - Carnivore 17. What is an independent variable? Variable I can change 18. What is a dependent variable? Variable that is measured 19. What are the parts to the cell theory? Cells are basic unit of structure, cells are basic unit of function, cells come from pre existing cells
