Question
Answer the following question.
Students were observing a film on Paramoecium. It underwent a process of reproduction. Teacher said it is due to cell division. But students objected and said that there was no disappearance of the nuclear membrane and no spindle formation, how can it be cell division? Can you clarify?
Solution
- Paramoecium is a unicellular organism. The division in Paramoecium occurs by amitosis.
- It is the simplest mode of cell division.
- In amitosis, nucleus elongates and a constriction appears. This constriction deepens and divides the nucleus into two daughter nuclei followed by the division of cytoplasm.
