Colchicine is a cell pison which arrests cell division at __ and can induce ___

Options

A. metaphase, parthenocarphy
B. anaphae, parthenocarpy
C. metaphase, polyploidy
D. anaphase, polyploidy

Answer

**Step-by-Step Solution:**

1. **Understanding Colchicine**: Colchicine is a chemical compound that acts as a cell poison. It is primarily known for its effects on cell division.

2. **Mechanism of Action**: Colchicine interferes with the formation of microtubules, which are essential for the proper segregation of chromosomes during cell division.

3. **Stage of Arrest**: The specific stage of the cell cycle where colchicine exerts its effect is during metaphase. In metaphase, chromosomes align at the cell's equatorial plane, and microtubules are crucial for pulling the chromosomes apart.

4. **Induction of Polyploidy**: When colchicine prevents the proper separation of chromosomes during metaphase, it can lead to the doubling of the chromosome number in the resulting cells. This phenomenon is known as polyploidy.

5. **Final Answer**: Therefore, the complete answer to the question is: "Colchicine is a cell poison which arrests cell division at metaphase and can induce polyploidy."
