Question

In frog, jelly around the eggs is deposited in
A.Ovary
B.Oviduct
C.Water after fertilization
D.Water during fertilization

Answer 1

Frogs live both on land and in freshwater and it belongs to the class Amphibia, phylum Chordata. In India, the most common species of frog found in the Rana tigrina. They are called poikilotherms which means cold-blooded and they go for summer sleep. They can camouflage from their predators like a snake. During very high temperatures they take shelter in deep burrows to protect themselves from extreme cold and extreme heat

Complete answer: Ovary- In frogs the ovaries are paired, multi-lobed organs and are attached to the dorsal side of the body wall by the double-layered extensions of the peritoneum called the mesovarium. The entire ovary continues with the peritoneum as the theca externa. Ovary’s each lobe is hollow and it has a continuous cavity with an additional seven to twelve lobes.
Oviduct-Laterally to each ovary is the densely coiled oviduct which is suspended from the dorsal body wall by the peritoneum double fold. The anterior ends are between the lateral peritoneum and the heart, at the liver lobe apex. At the anterior end of the slit-like ostium or infundibulum is ciliated and elastic walls. The female body cavity is entirely lined with cilia.
Hence the correct option is B, Oviduct.

Note: Body cavity eggs are often quite distorted because the ovulation process involves a rupture of the follicle and forcing out of the egg from a very muscular follicle. The egg is squeezed from the follicle, through a small aperture. The process looks like an Amoeba crawling through an inadequate hole. Ovulation (rupture and emergence of the egg) takes several minutes at laboratory temperatures and is not accompanied by hemorrhage. By the time the egg reaches the ostium (within 2 hours), as the result of ciliary propulsion, it is again spherical.
