About Multiple Fission in Plasmodium
Multiple fission is a reproductive process where a single parent cell divides into many daughter cells simultaneously. In Plasmodium, this occurs during the schizogony stage of its life cycle.
Biological Process:
- The Plasmodium cell grows significantly in size
- The nucleus undergoes repeated mitotic divisions without cytoplasmic division
- Numerous daughter nuclei form within the single cell
- Cytoplasm organizes around each nucleus
- The plasma membrane invaginates to form individual daughter cells
- The parent cell ruptures, releasing the daughter cells to infect new red blood cells
Significance in Malaria:
This process allows for rapid multiplication of the parasite within the host's red blood cells, leading to exponential growth and the characteristic cyclical fevers of malaria.
Key Characteristics:
- Produces 12-24 merozoites per schizont
- Completed in 48-72 hours (depending on Plasmodium species)
- Coincides with the rupture of red blood cells
- Responsible for clinical symptoms of malaria
