Question

Why are individual chromosomes more difficult to see during interphase than during mitosis?

Answer 1

This

Step-by-step explanation:

Individual chromosomes are more difficult to see during interphase because they are not tightly coiled and condensed. During mitosis they are tightly coiled, making them easier to see. ... In anaphase I of mitosis, sister chromatids separate.

Hope this helps!

Answer 2

In the interphase, they are really thin, just one strand which is only a few atoms wide (very challenging for an optical microscope and not too easy for the electronic one)
