How would you determine if a cell has progressed from prophase to metaphase?
(thank you!)

There is a very thin line between the two phases. Metaphase has begun when the chromosomes are lined up the middle of the cell, attached by spindle fibers to centrioles in both halves of the cells.

Prophase is when all of the chromosomes in a cell are randomly oriented throughout the cell. The cell is at metaphase when all of the chromosomes in the cell are perfectly lined up (at the metaphase plate). You can visualize this in live cultured cells (usually a cell line in a plate full of media or affixed to a coverslip) under a phase-contrast microscope. It's pretty cool to see this in live cells, b/c the progression from prophase to metaphase is relatively quick (approx. 5-10 minutes).

in pro phase chromosomes thickens and condense and in meta phase the chromosomes line up in the center of the cell ...
hint of remembering METAPHASE ( Meta - middle )
