If you are provided, with root-tips of onion in your class and asked to count the chromosomes, which of the following stages will be most conveniently observed?

• A. Metaphase
• B. Telophase
• C. Anaphase
• D. Prophase

Answer 1

The correct option is A Metaphase

Chromosomes are tightly coiled, shortest and most clearly visible in metaphase stage neatly arranged on the metaphase plate at the equator of the cell. Hence, metaphase stage is best suited to study the number and morphology of the chromosomes.

So, the correct answer is option A.
