explain the process of fertilisation in a frog
Answers
Answer:
Frogs show external fertilization. Frogs have no genital organ that can help them to deposit the sperms in the female frog’s body. Therefore, fertilization occurs outside the body of the female frog. The female frog releases the eggs. At the same time, the male frog also releases the sperms. The female frog can lay from one to several hundred eggs. These eggs and sperms are released in the water. Water is very necessary for fertilization in the case of frogs. This is because the eggs of frogs are jelly-like and they do not have any protective covering around them. Due to this reason the eggs are very prone to predators. Also, they are not viable for very long periods. On land, their drying can occur. Moreover, there would be no medium to cause fertilization. Therefore, the eggs are laid in water. The sperms swim to reach the eggs and fertilize them. After fertilization, the eggs develop into tadpoles. The tadpoles further undergo metamorphosis to form frogs.

Answer:
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them. However, a few species of frog use internal fertilization.
