Define: spermatogenesis,spermatozoa,spermatids,spermatophore.
Answers
Spermatogenesis : Spermatogenesis is the origin and development of the sperm cells within the male reproductive organs, the testes. Sperm cells are produced within the testes in structures called seminiferous tubules.
Spermatozoa : It is the mature motile male sex cell of an animal, by which the ovum is fertilized, typically having a compact head and one or more long flagella for swimming.
Spermatids : It is an immature male sex cell formed from a spermatocyte, which may develop into a spermatozoon without further division.
Spermatophore : Spermatophore is a protein capsule containing a mass of spermatozoa, transferred during mating in various insects, arthropods, cephalopod molluscs, etc.
Answer:
SPERMATOGENESIS
Spermatogenesis is the origin and development of the sperm cells within the male reproductive organs, the testes. Sperm cells are produced within the testes in structures called seminiferous tubules.
SPERMATOZOA
Spermatozoa (sperm) are the male sex cells that carry a man's genetic material. ... A sperm fertilizes a woman's egg (ovum) by breaking through the membrane that surrounds the egg. Sperm develop in a man's testicles. They are added to semen before a man ejaculates.
SPERMATID
The spermatid is the haploid male gametid that results from division of secondary spermatocytes. As a result of meiosis, each spermatid contains only half of the genetic material present in the original primary spermatocyte.
SPERMATOPHORE
a protein capsule containing a mass of spermatozoa, transferred during mating in various insects, arthropods, cephalopod molluscs, etc.
