This sounds like a question being asked of participants in a laboratory exercise, examining squashed onion roots stained to display chromosomes.
As such, it is best to answer it by doing the practical exercise!
You might expect prophase to be long (using the term "prophase" to include the stage "prometaphase" that is distinguished by some scientists). This is because the chromosomes have to condense from the extended form that they are in during interphase, to a supercoiled form suitable for movement later in mitosis.
Also, during prometaphase the chromatids become attached to spindle fibers, and the cell has a checkpoint at this stage, that usually prevents non-disjunction (sending the wrong number of chromosomes to the daughter-nuclei).

What phase of the cell cycle does mitosis start?
Mitosis begins during the M phase of the cell cycle, which is also known as the mitotic phase. This phase includes mitosis, where the nucleus divides, and cytokinesis, where the cytoplasm divides, resulting in two daughter cells.
Is Sphase a phase of mitosis?
Yes it is a phase of mitosis. It the the phase in thich the chromosomes duplicate. As a result each chromosome ha 2 sister chromatids
Which phase of mitosis is the last phase that chomatids are together?
metaphase
What phase of mitosis is the last phase that the chromatids are together?
metaphase
The final phase of mitosis is-?
The final phase of mitosis is called Telophase. The other stages are Prophase, Metaphase and Anaphase.
How does mitosis differ between the onion root and the roundworm?
The only difference between vegetal (onion) cells and animal (roundworm) is not quite in mitosis, but in citokinese (not a mitosis phase since mitosis refers to nucleus division). Vegetal cells have a thick wall rounding the cell which needs different means to split than the membrane in animal cells

Does DNA replicate in mitosis?
No, DNA replicates in the S phase of the cell cycle, which occurs before mitosis. This ensures that each daughter cell receives an identical copy of the genetic material during cell division.

Yes it is a phase of mitosis. It the the phase in thich the chromosomes duplicate. As a result each chromosome ha 2 sister chromatids

Which phase encompasses all of the stages of mitosis?
The phase that encompasses all stages of mitosis is the M phase, also known as the mitotic phase. This phase includes prophase, prometaphase, metaphase, anaphase, and telophase. During mitosis, the cell divides its nucleus into two genetically identical daughter nuclei.
Which phase occurs directly after G2?
M Phase
What phase prepares for mitosis?
interphase
