After meiosis is the cell a completed sperm or does it go through other steps to attach the locomotion tail.

What is the process to produce a high number of mitochondria

No.

Yes. The tail grows from the cell rather than being ‘attached’. This site seems to have some good graphics and explanations:

Mitochondria reproduce in the cell by simple binary fission. The number of mitochondria in a given cell type is regulated by intrinsic factors. I assume that the spermatogenesis developmental process stimulates a lot of mitochondrial fission at either the spermatogonium, spermatocyte or spermatid stage so that the mature spermatozoa inherit lots of them.
