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

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.

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.

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.

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.

Which structure is responsible for controlling the movement of substances into and out of a bacterial cell?
- A.
  
  Cell wall
- B.
  
  Cytoplasm
- C.
  
  Ribosome
- D.
  
  Plasma membrane
Correct Answer
D. Plasma membrane

Explanation
The plasma membrane in bacterial cells is a critical structure that controls the movement of substances into and out of the cell. It is a selectively permeable membrane, meaning it allows certain molecules to pass while blocking others. The plasma membrane also plays a role in energy production and communication with the environment. While the cell wall provides shape and structural support, it does not regulate molecular traffic. The cytoplasm houses internal components, and ribosomes are involved in protein synthesis but do not control substance movement.

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.

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.

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.
