Solution
The correct option is A A - C - B - D In multiple fission, several offspring are formed from a single individual. In plasmodium, the nucleus of the cell divides repeatedly forming many nuclei. The cytoplasm surrounds each nucleus formed and many daughter cells are formed within the cyst which is already formed before division. This cyst breaks down to give multiple organisms.
To put it short, the sequence of events in multiple fission would be:
- Unfavourable conditions spark the fission
- Cyst formation occurs
- Multiple nuclei form from the nucleus
- Cyst breaks to give new organisms
