In what phase of mitosis does a typical onion root tip meristem cell spend the most of its time?

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).

When does mitosis begins and end?
The first phase of mitosis is prophase. The last phase of mitosis is telophase.
What phase of the cell cycle does mitosis start?
Mitosis is a phase of the cell cycle. It occurs after the G2 phase.
What is a usual sign of the change of the apical meristem from the juvenile to the mature phase?
A Change in the Morphology
What phase of mitosis is the short second phase?
Metaphase
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
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

What phase of the cell cycle does mitosis start?

Is lunar phase a phase of mitosis?
No.
What phase of mitosis where the cytokinesis is completed?
Telophase is the last phase of mitosis. Cytokinesis is not actually a part of mitosis but happens after.
What is the last phase of mitosis?
The 4 phases of Mitosis are: Prophase, Metaphase, Anaphase, and Telophase.
Mitosis also known as?
The M phase in cell cycle is the mitosis phase, where the cell performs mitosis.
What is the longest phase of mitosis?
the longest phase of mitosis is prophase.Interphase is the longest phase in mitosis. It involves 3 parts: G1: Growth of the cell, S phase: organelles are replicated, and G2: where cells prepares for division.Prophase =)
What is a usual sign of the change of the apical meristem from the juvenile to the mature phase?
A Change in the Morphology
What happens during m phase (mitosis) of the cell cycle?
Nuclear division by mitosis or meiosis
Which phase occurs before mitosis or meiosis?
Inter-phase occurs before mitosis or meiosis.
Does DNA replicate in mitosis?
no DNA replicates before mitosis. It replicates in the S phase of inter phase
