What is being so carefully sorted in mitosis?

This happens in the S phase of Mitosis, this is when plant cells make copies of chromosomes, so during mitosis, they need to sort carefully and make sure that each cell gets one of each chromosome. 

So chromosomes are the thing that is being so carefully sorted in mitosis.

Hope this helps! >.<
