Question

In which of the following organisms, multiple fission is a means of asexual reproduction ?

• A. Yeast
• B. Leishmania
• C. Paramoecium
• D. Plasmodium

Answer 1

The Correct Option is D

Step 1: Defining Multiple Fission:
Multiple fission is an asexual reproduction method where one organism splits into numerous offspring at once.
This is common in certain single-celled organisms, mainly protozoa and some algae.

Step 2: Selecting the Appropriate Organism:
Let's examine the provided choices and how they reproduce:

- Plasmodium:
Plasmodium, responsible for malaria, reproduces via multiple fission, specifically termed schizogony. This involves multiple nuclear divisions followed by cytoplasmic division, yielding many daughter cells.

- Amoeba:
Amoebas reproduce through binary fission, where a single cell divides into two identical daughter cells.

- Yeast:
Yeast primarily reproduces by budding, a process where a small outgrowth detaches to form a new organism.

- Bacteria:
Bacteria reproduce via binary fission, with one bacterium dividing into two identical bacteria.

Step 3: Final Determination:
The organism that employs multiple fission for asexual reproduction is Plasmodium.
