  1. Mitosis divides the chromosomes in a cell nucleus to make an exact replica. Mitosis is not essential for sexual reproduction.

    meiosis  is a process of reduction division in which the number of chromosomes per cell is cut in half.

    Meiosis is essential for sexual reproduction  

    Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission. Each cell has half the number of chromosomes as the parent cell.


  2. so  technically no

    it's the the phase of the cell cycle in which the cell spends the majority of its time and performs the majority of its purposes including preparation for cell division

    Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.

    This cycle begins when the cell is produced by mitosis and runs until the cell undergoes its own mitosis and splits in two. The cycle is divided into distinct phases: G1 (gap 1) S (synthesis), G2 (gap 2), and M (mitosis). As you can see, mitosis only occupies a fraction of the cycle. The rest of the time-phases G1 through G2—is known as interphase.

    Scientists used to think of interphase as a resting phase during which not much happened, but they now know that this is far from the truth.

  3. As far as I know, your question is sort of hard to answer; not unanswerable, just a lot more complex than you think.

    Here's fact number one: interphase is the longest phase a cell stays in compared to the other stages like the s phase, or g phase, etc.

    Fact 2: during this stage the cell is producing the necessary "materials" required for the cell to split.

    So here's the thing, mitosis is not necessarily the splitting of the cells cytoplasm to create two new cells, that's why muscle cells have more than one nucleus. But certain cells need to be replaced at certain rates and so undergo interphase and meiosis more often than other cells. How long the cell remains in each stage is monitored, that's why we have things like tumors/cancer, which are uncontrolled rapidly dividing cells occuring at a much faster rate than normal. So therefore we can't say that interphase in mitosis is necessarily longer or shorter or exactly the same as that of meiosis.  Plus, we need to keep in mind that meiosis might occur at different rate for males as it does in females; I'm not sure, hence the "might."
