Solution
Spermatids and spermatocytes
Spermatids are immature, undifferentiated haploid male gametes.
Spermatocyte is a cell produced at the second stage in the formation of spermatozoa, formed from a spermatogonium and dividing by meiosis into spermatids
Spermatids and spermatocytes are haploid.
Haploid refers to the presence of a single set of chromosomes in a cell.
The only difference is that secondary spermatocytes contain duplicated chromosomes having two chromatids each whereas spermatids contain chromosomes with one chromatid only.
