Binary Fission

Question 1

What is Binary Fission

Answer 1

Binary Fission is the process by which prokaryotic organisms, divide and reproduce.

Question 2

List the organelles of a prokaryotic organism.

Answer 2

• Cell wall
• Cell membrane
• Cytoplasm
• Nucleoid (Circular DNA)
• Plasmids
• Flagellum

Question 3

Describe what happens in binary fission in a bacteria?

Answer 3

Binary fission only occurs when the bacteria cell has grown.

The bacteria duplicates its genetic materials (Nucleoid and Plasmids). This duplicated genetic materials then move to the other side of the bacteria cell. Shortly after, The bacteria forms a new cell wall that divides the genetic materials (Nucleoids and Plasmids) into two. Once this is done the bacteria cell splits into two new bacteria cells.

Question 4

NOTE:

Answer 4

Some bacteria can divide very 20 minutes

Question 5

A bacteria cell has a mean division time of 30 minutes.

How many cells would it produce in 3 Hours?

Answer 5

First of we have to change 3 hours into minutes. So, we do
3 × 60 = 180
3 hours = 180 min

Since, the bacteria cell divides every 30 minutes we divide 180 by 30.
180/30 = 6

Since, the bacteria cell was originally 1 cell.
We can say within 3 hours the cell would make:
1×2×2×2×2×2×2
which in simple term is
1× 2⁶.= 64
