Question

During binary fission in Amoeba which of the following organelles is duplicated?

• A. Plasma membrane
• B. Nucleus
• C. Contractile vacuole
• D. All of the above
  

Answer 1

The correct option is B Nucleus

• In the process of binary fission one parent cell divides to produce two equal cells that give rise to two new individuals, e.g., bacteria and Amoeba.
• Hence in Amoeba nucleus in the parent cell is duplicated before it divides and forms 2 separate individuals so that both can get complete genetic material.

So, the correct answer is option is B.
