Final answer:
Spermatids leave the seminiferous tubules and mature into spermatozoa in the epididymis, where they develop the capability to swim and are stored until ejaculation.
Step-by-step explanation:
The cell type that leaves the seminiferous tubules and matures in the epididymis is known as spermatids. These cells, upon release from the seminiferous tubules, are non-motile and require further development. It is within the epididymis that spermatids undergo morphological changes during spermiogenesis, transforming into spermatozoa. This maturation process includes the development of a tail and the ability to swim, which is essential for fertilization. The mature sperm are then stored in the epididymis until ejaculation occurs.
The cell type that leaves the seminiferous tubule and matures in the epididymis is the spermatids. Spermatids are the least mature cells in the seminiferous tubules, and they undergo maturation in the epididymis to become mature sperm cells. During this maturation process, spermatids grow a tail and lose some of the cytoplasm from the head, becoming capable of swimming.
