FAQs on Binary Fission Video Lecture - Biology Class 11 - NEET

1. What is binary fission?
Ans. Binary fission is a type of asexual reproduction in which a single parent organism divides into two identical daughter cells. It is commonly observed in prokaryotic organisms such as bacteria.
2. How does binary fission occur?
Ans. Binary fission occurs in three main steps. First, the DNA of the parent cell replicates. Then, the cell elongates and the replicated DNA moves to opposite ends of the cell. Finally, the cell membrane pinches inward, dividing the cell into two daughter cells.
3. What is the purpose of binary fission?
Ans. The purpose of binary fission is for organisms to reproduce and multiply their population. It allows for rapid and efficient reproduction without the need for a mate or the production of gametes.
4. Can binary fission occur in multicellular organisms?
Ans. No, binary fission is typically observed in unicellular organisms such as bacteria. Multicellular organisms, on the other hand, reproduce through other methods such as sexual reproduction or mitosis.
5. What are the advantages of binary fission?
Ans. Binary fission offers several advantages. It allows for quick reproduction and population growth, as each parent cell can produce two daughter cells. It also ensures genetic stability as the daughter cells are genetically identical to the parent cell. Additionally, binary fission does not require the energy and resources involved in finding a mate or producing gametes.
