Question

Identify the type of reproduction shown in the diagram given below: 

• A. Budding
• B. Fragmentation
• C. Spore Formation
• D. Binary Fission

Hint:

In Binary Fission, the parent identity is lost as it becomes the two daughter cells, unlike Budding (e.g., in Yeast) where the parent cell remains intact after the bud detaches.

Answer 1

The Correct Option is D

The diagram shown is a classic representation of Binary Fission, a type of asexual reproduction commonly observed in unicellular organisms such as bacteria and amoebae. Let's examine why this is the correct choice:

1. Understanding Binary Fission: Binary fission involves the division of a single organism into two separate organisms. The process begins with the duplication of the genetic material, followed by the division of the cytoplasm, resulting in two daughter cells that are genetically identical to the parent cell.
2. Steps in the Diagram:
   • The diagram illustrates the organism initially enlarging and replicating its DNA.
   • This is followed by the constriction forming a cleavage furrow.
   • Eventually, the organism splits into two distinct entities.
3. Comparison with Other Options:
   • Budding: In budding, a new organism grows as an outgrowth from the parent and detaches once mature; this is not shown in the diagram.
   • Fragmentation: Fragmentation involves breaking into pieces, each growing into a new organism, unlike the depicted process.
   • Spore Formation: This process involves the organism producing spores that develop into new organisms, which is different from what is shown.

Thus, the correct answer is Binary Fission.
