believe it or not, mitosis always takes place in the cell; it never stops, even for a fraction of a second! However, there has been a stage called Interphase, which was once incorrectly termed as the Resting Phase of a cell. Scientists have proved that this is not so, for in this stage, the cell engages in different activities to prepare for the next cell division, such as: replication of the DNA, replication of centrioles, formation of new cellular organelles, chromosomes appear as long chromatic threads swollen at intervals into visible chromatic granules, and lastly, the cell synthesizes and stores enough energy, ready for the division! Have I answered your question? -B.C.O :-)
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
A duplication of the chromosomes is what must happen before meiosis can begin.
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
A zygote is created by the fertilization of two haploid cells created by meiosis. Because a zygote is fertilized by two haploid cells, it is diploid. It then has to divide and grow though mitosis like any other body cells.
No, the stages of mitosis do not occur simultaneously in a meristem. Mitosis is a sequential process that involves several distinct stages: prophase, metaphase, anaphase, and telophase. Each stage must be completed before the next one can begin.

Meiosis precedes fertilization so maybe you mean mitosis. A fertilized egg does not die but becomes known as a zygote. The zygote spends roughly a half hour as a single cell before mitosis begins.
they have to duplicate
Both processes begin with similar events, including chromosome replication.
The Metaphase of mitosis in a eukaryotic cell. I don't know for prokaryotic and viruses don't. Also Metaphase in Meiosis 1 and 2.

Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
