Questions and Answers
  • 1. 

    Bacteria are _______, meaning they have _______ _____________________

    • A.

      Prokaryotes; no nucleus

    • B.

      Prokaryotes; no DNA

    • C.

      Eukaryotes; no nucleus

    • D.

      Eukaryotes; no DNA

    Correct Answer
    A. Prokaryotes; no nucleus
    Explanation
    Remember, bacteria are examples of prokaryotes. This means they have NO nucleus. Remember PRO= NO

  • 2. 

    You are looking at a sample under the microscope to see if your patient has a bacterial infection. When you look in the microscope, you see something that looks like this. Is it a bacterium?

    • A.

      Yes, this is a bacterium

    • B.

      No, this is not a bacterium

    Correct Answer
    B. No, this is not a bacterium
    Explanation
    Nope! Look at that big nucleus in the middle. Remember, a bacterium does not have a nucleus! The more complex a cell is, the less likely it is to be bacteria.

    Rate this question:

  • 3. 

    Which bacteria cell part goes in the box labelled a? 

    • A.

      Flagella

    • B.

      Chromosomal DNA

    • C.

      Ribosomes

    • D.

      Plasma Membrane

    Correct Answer
    A. Flagella
    Explanation
    Flagella are whip-like structures found on the surface of bacteria that are responsible for their movement. They act like tiny propellers, allowing bacteria to swim and navigate through their environment. Therefore, the correct answer is flagella as it is the bacterial cell part that goes in the box labelled a.

    Rate this question:

  • 4. 

    Which bacteria structure is labelled with the star?

    • A.

      Cell Wall

    • B.

      Capsule

    • C.

      Ribosome

    • D.

      Flagella

    Correct Answer
    B. Capsule
    Explanation
    The structure labelled with the star is the capsule. A capsule is a protective layer that surrounds the cell wall of some bacteria. It helps the bacteria to evade the immune system and provides protection against harsh environmental conditions. Capsules are often composed of polysaccharides or proteins and can vary in thickness and composition among different bacterial species.

  • 5. 

    Which bacteria cell part goes in the box labelled b?

    • A.

      Flagella

    • B.

      Chromosomal DNA

    • C.

      Ribosomes

    • D.

      Cell Wall

    Correct Answer
    C. Ribosomes
    Explanation
    Ribosomes are the cell part that goes in the box labelled b. Ribosomes are responsible for protein synthesis in the cell. They are composed of RNA and protein and can be found either free in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes play a crucial role in translating the genetic information from the DNA in the nucleus to produce proteins that are essential for various cellular functions.

  • 6. 

    Which bacteria cell part goes in the box labelled with the star?

    • A.

      Flagella

    • B.

      Chromosomal DNA

    • C.

      Plasmid DNA

    • D.

      Cell Wall

    Correct Answer
    C. Plasmid DNA
    Explanation
    The plasmid DNA is the small circular DNA. The chromosomal DNA is the larger bundle of DNA

    Rate this question:

  • 7. 

    Which bacteria cell part goes in the box labelled with the star?

    • A.

      Flagella

    • B.

      DNA

    • C.

      Plasma Membrane

    • D.

      Cell Wall

    Correct Answer
    C. Plasma Membrane
    Explanation
    The plasma membrane is the correct answer because it is the outermost boundary of a bacterial cell and acts as a protective barrier. It controls the movement of substances in and out of the cell, allowing it to maintain its internal environment. The plasma membrane also plays a role in cell signaling and communication. Therefore, it is an essential part of a bacterial cell and fits the description of the cell part that goes in the box labelled with the star.

    The hair like structure in bacteria cell are called

    • A.

      Nucleus

    • B.

      Flagella

    • C.

      Mitochondria

    • D.

      Cell wall

    Correct Answer
    B. Flagella
    Explanation
    Flagella are the hair-like structures found in bacteria cells that are responsible for their movement. They act like a whip, propelling the bacteria forward or allowing them to move in a rotational manner. The flagella are made up of a protein called flagellin, which forms long, whip-like structures that extend from the surface of the cell. These structures can rotate and move in response to various stimuli, allowing the bacteria to swim towards or away from certain substances or environments. The presence of flagella is a characteristic feature of many bacterial species and plays a crucial role in their survival and dispersal.

  • 9. 

    Ribosomes are also found in bacteria cell.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Ribosomes are small, spherical organelles found in all types of cells, including bacteria cells. They are responsible for protein synthesis, where they read the genetic information from the DNA and use it to assemble proteins. Therefore, it is true that ribosomes are also found in bacteria cells.

    Rate this question:

  • 10. 

    Bacteriophage is a virus that can infect bacteria.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Bacteriophage is a type of virus that specifically infects bacteria. Unlike other viruses that infect animals or plants, bacteriophages have the ability to attach to bacterial cells and inject their genetic material into them, causing the bacteria to produce more phages and eventually leading to the destruction of the bacterial cell. Therefore, it is true that bacteriophages can infect bacteria.
