  1. Viruses, Bacteria, Protists, and Fungi Table of Contents Viruses Bacteria Protists Fungi

  2. Viruses Virus Shapes The leglike structures on the bottom of the T4 bacteriophage keep the virus firmly in place as it infects a cell.

  3. Viruses Alive or Not? Which of these mystery objects is not alive?

  4. Viruses Virus Sizes The Streptococcus bacterium is a round organism that causes strep throat. If it is 10 times larger than the cold virus, what is its size?

  5. Viruses Virus Structure and Invasion Some viruses are surrounded by an outer membrane envelope.

  6. Viruses Vaccine Protection Influenza (flu) and other diseases can be prevented by vaccines.

  7. Viruses Viruses can cause disease around the world.

  8. Bacteria Bacterial Cell Structure A bacterial cell that lacks a flagellum can be carried from place to place by air, water, or other organisms. What are the missing names of the cell structures?

  9. Bacteria Complete the table that lists how the bacteria get energy, whether they need oxygen, and how to destroy them.

  10. Bacteria Asexual and Sexual Reproduction

  11. Bacteria Endospore Formation The panels illustrate endospore formation.

  12. Bacteria Level of Oxygen What might happen to the level of oxygen when a colony of autotrophic bacteria grows quickly under a sun lamp? When the size of the colony remains the same? When the bacteria get put into the shade?

  13. Bacteria Bacteria and the Environment What are some roles of bacteria in nature?

  14. Protists Amoeba This amoeba’s pseudopods surround and trap a food particle. What is the second step of this process?

  15. Protists Protozoans With Flagella The protozoan Giardia has eight flagella and two nuclei. How is the movement of oars on a boat similar to the movement of the flagella?

  16. Protists Protozoans With Cilia Paramecia use cilia to move through water. How is the movement of oars on this boat similar to the movement of cilia?

  17. Protists Amoebas How will the amoebas respond to bright light? Why is it important that they respond to light?

  18. Protists Functions of Algae Algae play important roles in the environment. What are the functions of each type of algae?

  19. Protists Soybean Crop Loss The graph shows crop loss in metric tons in the United States between 2002 and 2005. How can the vertical axis be labeled? How did the soybean crop loss change? What would be a good title for the graph?

  20. Fungi Structure of a Mushroom What function might the underground hyphae in this mushroom perform?

  21. Fungi A dot of mold has started growing in the middle of each of two dishes containing the same bacteria. What happened by day two? Are the two dots of mold the same type of fungus?

  22. Fungi What in the World? Rico is taking a trip around the world. Follow him as he encounters viruses, bacteria, protists, and fungi in the environment.
