bacterial cell

Question 1

Question (Side A)

Answer 1

Answer (Side B)

Question 2

What are Flagella?

Answer 2

Tail-like structures that rotate like a propeller to allow the cell to move through liquids.

Question 3

What are Pili?

Answer 3

Tiny “hair-like” structures used for attachment to surfaces (like the digestive tract) and for transferring genetic material between bacteria.

Question 4

What is a Slime Capsule?

Answer 4

An outer layer that protects bacteria from drying out or poisonous substances, and helps them stick to smooth surfaces.

Question 5

What is a Plasmid?

Answer 5

A small, circular piece of DNA that stores “extra” genes (e.g., antibiotic resistance) not usually needed for day-to-day survival.

Question 6

Define Binary Fission.

Answer 6

The process of asexual reproduction in bacteria where one cell divides into two genetically identical daughter cells.

Question 7

Step 1 of Binary Fission?

Answer 7

Replication: The circular DNA and plasmids replicate (copy themselves).

Question 8

Step 2 of Binary Fission?

Answer 8

Elongation: The cell grows larger and the two sets of DNA move to opposite ends (poles) of the cell.

Question 9

Step 3 of Binary Fission?

Answer 9

Septum Formation: The cytoplasm begins to divide and a new cell wall (septum) starts to form down the middle.

Question 10

Step 4 of Binary Fission?

Answer 10

Division: The cell splits into two daughter cells. Each has one copy of the main DNA but may have a variable number of plasmids.
