Which part of ovary in mammals acts as an endocrine gland after ovulation?A. StronaB. Germinal epitheliumC. Vitelline membraneD. Graafian follicle |
|
Answer» Correct Answer - D Release of ovum from the ovary is called ovulation The Graafian follicle rises to the surface sends out a protuberance or stigma and everts to release the ovum into peritonearl cavity. The empty Graafian follicle contains. A blood continue to proliferate develop yellow carotene pigment or lutein and get converted into lutein cells. This converts the ruptured follicle into yellow body called corpus luteum. it becomes terprory endocrine gland secreting progesterone with small quantity of estrogen. |

Pattern of cleavage in egg of Frog isA. MeroblasticB. Holoblastic unequalC. Holoblastic equalD. All of the above |
|
Answer» Correct Answer - B (B) Types of Cleavage: Type of cleavage in an egg is determined by amount and distribution of yolk. 1. Holoblastic cleavage: Cleavage of zygote is complete and divide 2 blastomores completely. This is of 2 types: (i) Equal holoblastic cleavage: It forms equal blastomeres. e.g.: Human, starfish Alecithal and microlecithal egg. (ii) Unequal holoblastic cleavage: It forms 2 unequal blastomeres. e.g.: Frog, dog fis: Mesolecithal egg. (2) Meroblastic cleavage: In this cleavage is incomplete or partial or parietal and the division is confined to the animal pole. Yolk is not divided. It is of two types: ltbtgt (i) Discoidal cleavage: The cleavage confined only to the disc area at the animal pole. e.g.: Reptiles, birds (chick and pigeon) and egg laying mammals : Megalecithal egg. (ii) Superficial cleavage: The cleavage is restricted to the superficial region of egg. e.g.: Insects (Arthropods), Centrolecithal eggs. |

Acromosome reaction in sperm is triggered by:A. capacitationB. release of lysinC. influx of `Na^(+)`D. release of fertilisin |
|
Answer» Correct Answer - D (d) Ovum secretes a chemical substance, called fertilisin which has number of spermophilic sites on its surface where the sperm of species specifuc type can be bound by their antifertilisin site. This fertilisin-antifertilisin reaction triggers acrosome reaction. the main aim of this reaction is to thin out the number of sperms to reduce the chances of polyspermy. |
