Question

What does the reproductive system of a frog do? How is it similar to the human reproductive system?

Answer 1

Hint: Frogs show sexual dimorphism. They are unisexual organisms that have distinct physical and sexual characteristics and have different external appearances.

Complete answer:
Frogs are the organisms belonging to the Order Anura, Class Amphibia, Phylum Chordata, and Kingdom Animalia. They are a cosmopolitan and diverse group of animals that are short-bodied, tailless, have bulgy eyes, and slimy skin. The sexes are different. The reproductive structures in frogs are present separately in males and females. The male reproductive system consists of- a pair of the testis, vasa efferentia (10-12 in number), urogenital ducts, and cloaca. The male gametes or sperms are formed in the testis. They are carried by the vasa efferentia and urinogenital ducts in the form of semen and are further released out by the opening called the cloaca.
The female reproductive system consists of- a pair of ovaries and oviducts. The female gametes are formed in the ovary. They are taken by the oviducts and released out at the opening of the cloaca.

During the process of reproduction, the male and female frogs enter a mating posture called amplexus. This posture ensures that the sperm meets the eggs. The male and female frogs release their gametes in the water body where the fertilization occurs. The egg mass is formed by the fusion of gametes, which later hatch into a tadpole. Metamorphosis occurs and results in the formation of an adult frog.

1)The similarities between the frog and the human reproductive system are limited.
2)They both are sexually dimorphic.
3)They both are unisexual.
4)They both have distinct organs for the production of gametes.
5)They both produce male gametes in the testis and the female gametes in the ovaries.
6)They both have vasa efferentia and oviducts for the transportation of gametes.

Note: The major difference between the reproductive system of males and frogs lies in their fertilization space. Humans have internal fertilization, while frogs have external fertilization. The development of a tadpole from the egg mass occurs outside the female body. The tadpole later metamorphoses to become an adult frog.
