Primary spermatocytes are immature cell with having diploid (2N) number of chromosomes
Explanation:
Spermatozoon
It is the term used to describe the motile mature sex cell of the male organism. These cells have a haploid (N) number of chromosomes. Spermatozoon has one or more swimming flagella with a head-on anterior side. This cell is ready to fertilize with the female egg cell to produce a zygote.
Primary spermatocytes
This is a diploid cell having a 2N number of chromosomes. Primary spermatocyte refers to the cell before the process of Meiosis I. After Meiosis I secondary spermatocytes are produced which have half the number of chromosomes.
