Back to: MICROBIOLOGY 100 LEVEL
Welcome to class!
Hello, my wonderful learner! I’m so happy to see you again, ready to add another important piece to your science puzzle. Today, we’re going to learn about binary fission—the special way bacteria and some other tiny organisms make new copies of themselves. Imagine if you could split into two just like that—doubling yourself in no time! That’s exactly what binary fission is all about. Let’s find out how it happens.
Binary Fission
What is Binary Fission?
Binary fission is a simple method of reproduction used by bacteria and some single-celled organisms. The word “binary” means two, and “fission” means splitting. So, binary fission literally means “splitting into two.” It’s how bacteria make new cells without needing a partner.
Think of it like a magic mirror that can make an exact copy of you!
How Does Binary Fission Work?
Here’s how the process goes, step by step:
First, the bacterial cell’s DNA, which contains all its instructions, copies itself so there are two identical sets.
The cell then grows bigger, and the two copies of DNA move to opposite ends of the cell.
The cell’s body, called the cytoplasm, begins to divide, forming a new cell wall between the two DNA copies.
Finally, the cell splits into two identical daughter cells. Each daughter cell has the same DNA and is ready to grow and divide again.
This process can happen very fast—sometimes a bacterium can divide every 20 minutes under the right conditions!
Why is Binary Fission Important?
Binary fission allows bacteria to reproduce quickly and colonise new environments. This is why sometimes food spoils fast or infections spread quickly in the body.
It’s also why washing hands, keeping things clean, and proper medical care are so important—because bacteria can multiply rapidly if given the chance!
Summary
- Binary fission is a method of reproduction where one bacterial cell splits into two identical cells.
- It involves copying DNA, growing, and splitting the cell.
- It happens very quickly, allowing bacteria to multiply fast.
- This rapid reproduction is why bacteria can spread and cause infections.
