The set of two successive cell divisions that serve to separate homologous chromosome pairs prior to the formation of gametes (sperm and eggs). The major purpose of meiosis is the precise reduction in the number of chromosomes by one-half, so that a diploid cell can create haploid gametes. Meiosis is therefore a critical component of sexual reproduction

Meiosis is cool, because it halves the amount of chromosomes in a cell, making sperm and eggs which are vital for reproduction. After sperm and eggs are created, one of each get together and bam! You've got a full set of DNA! (recap, full set of DNA --meiosis---> half set of DNA as sperm or eggs----->sperm and egg get together---->full set of DNA and a new organism).
Without meiosis, all we'd have is asexual reproduction which means we wouldn't have the variety that we have. We'd all be versions of one of our parents, they probably would have budded off an arm or something and here we would be. Boring! and no way for natural selection to occur. Hope this answer helps!
PS This is the same for plants too as I noticed this was under botany. Plants have eggs and pollen (sperm) is the only difference.

that's the approach which splits the two chromosome cellular right into a a million chromsome cellular making an allowance for the union of mono chromosome cells in sexual reproduction to combination and combine diverse DNA strands

Meiosis creates sex cells...that is, sperm and eggs, which are necessary to reproduce sexually.
