Question

Axial filament sperm is formed by

Answer 1

Hint: The male gamete or sperm has 4 parts- head, neck, body and tail. The head contains the nucleus and the acrosome. The neck contains centrioles i.e. distal centriole and the proximal centriole.

Step by step answer:Axial filament sperm is formed by distal centriole.
The male gamete or sperm has 4 parts- head, neck, body, and tail. The head contains the nucleus and the acrosome. The neck contains centrioles i.e., distal centriole and the proximal centriole. The function of the distal centriole is to form the axial filament. The centrioles help in cell division after fertilization. Mitochondria provide energy for the movement of the sperm. The axial filament is the proper term for the tail, in which it helps the sperm to travel to the ovum. Sperm usually consist of two morphologically and functionally distinct regions enclosed by a single plasma membrane: the tail, which propels the sperm to the egg and helps it to burrow through the egg coat, and the head, which contains a condensed haploid nucleus. The tests are composed of coiled structures called seminiferous tubules, which are the sites of sperm production. The structure on top of the seminiferous tubules in the testes is the epididymis. The sperm migrate from the seminiferous tubules to the epididymis.
Additional information: Sperm cells are gametes (sex cells) that are produced in the testicular organ (gonad) of male human beings and animals. Spirochaetes are distinguished from other bacterial phyla by the location of their flagella, sometimes called axial filaments, which run lengthwise between the bacterial inner membrane and outer membrane in periplasmic space. These cause a twisting motion which allows the spirochaete to move about.

Note: The scientific name for sperm is spermatozoa, spermatozoan, spermatozoon. Sperm, also called spermatozoon, plural spermatozoa, male reproductive cell, produced by most animals.
