Yes, amoebae use mitosis.
Amoeba Reproduction and Mitosis
Amoebae reproduce asexually through a process called binary fission, which involves mitosis. This process is how a single amoeba grows and multiplies to create two new amoebae.
How Mitosis Works in Amoebae
The reference states, "Amoeba multiplies by simple mitotic cell division". This means that the amoeba's cell divides using mitosis, resulting in two genetically identical daughter cells.
Here's how it generally works in amoebae:
- DNA Replication: The amoeba's DNA is duplicated within its nucleus.
- Nuclear Division: The nucleus divides through mitosis, distributing the replicated DNA equally into two new nuclei.
- Cell Division: The amoeba cell then physically divides into two separate daughter cells.
- Daughter Cells: Each daughter cell is a new, independent amoeba, genetically identical to the parent amoeba.
Key Points:
- Mitosis is the primary method of reproduction for amoebae.
- The reference confirms that amoebae increase in number through mitotic cell division.
- This process leads to rapid population growth under favorable conditions.
- Growth is synchronous with reproduction, meaning that the increase in amoeba size and number occurs simultaneously.
Why Mitosis is Important for Amoeba
Mitosis ensures that each new amoeba receives a complete and identical copy of the parent amoeba’s genetic material. This is important for maintaining the genetic stability of the species.
