Write the function of each of the following (i)Seminal vesicle (ii)Scutellum (iii)Acrosome of human sperm -Biology
by

1 Answer

Answer :

(i)Seminal vesicle spermatogenesis It secretes an alkaline fluid that helps in neutralising the acidity of the vaginal tract and thereby increase the lifespan of sperms. Secretion of seminal vesicle is also a source of nutrition for the sperms. (ii) Scutellum It is a tissue present in seed to absorb food from the adjacent endosperm and develop into growing embryo. (iii) Acrosome It is the cap-like covering or structure that is present at the tip of the sperm (male gamete). The acrosome contains enzymes, which help the sperm enter into the cytoplasm of the ovum and thus helps in fertilisation.
