- Draw well labeled diagram of T.S. of ovary?V. Sequence of Events: Spermatogenesis Thousands of sperm are produced each second. Insert numbers in the spaces provided to arrange the events of spermatogenesis in the proper order. A Daughter cells of spermatogonia differentiate into slightly larger cells called primary spermatocytes, which move toward the lumen of the seminiferous tubule. _B Spermatids differentiate to form heads and tails and eventually transform into mature spermatozoa (sperm), each with 23 chromosomes _C Each secondary spermatocyte divides to form two spermatids. D Spermatogonia in the walls of the seminiferous tubules divide by mitosis to produce two daughter cells, each with 46 chromosomes. E. Through meiosis, the primary spermatocyte yields two genetically unique secondary spermatocytes, each with 23 chromosomes.B. Draw and label the cross section of the cat ovary (using HPO). Label all the oogenic cells. C. Draw the mature Graafian follicle and label the parts.
