Answer 2

In onion root tip, number of chromatids in metaphase stage of mitosis will be 32.

Explanation:

The entire cell undergoes cell division through mitosis or meiosis. The germ cell divides mitotically and all other cells except germ cells divide meiotically. The mitosis cell division occurs through four stages namely:

• Intephase
• Metaphase
• Anaphase
• Telophase

In onion root tip, during metaphase stage 16 chromosomes are present. Chromatids refer to the thread like structure of chromosomes. Double the chromosome number gives value for chromatids. As number of chromosome is 16, when we double it we get 32 as answer. Thus 32 chromatids are present in the metaphase stage of onion root tip.
