Zoology - Human Reproduction Question with Solution | TestHub

The tail is a very long tapering vibratile part of sperm, so the tail brings about the movement of sperm. The tail of the sperm is called the flagellum, It provides motility to the sperm. It is made up of axoneme (the central skeleton with 11 microtubules), a thin cell membrane covering it and a spirally arranged mitochondria. The back and forth movement of the tail makes the sperm to move. ATP produced by mitochondria supplies the energy for this process.
