Answer 1

Answer:

External Fertilisation, mainly takes place in amphibians.

• Medium Require : Water

____________________________

♦ Fertilisation is a process in which male gamete and female gamete fuses together to form zygote.

Both male and female gametes are haploid and zygote is diploid.

There are two types of fertilisation :

• Internal Fertilisation : Fusion takes place inside the female body.

Examples : Mammals including humans, etc.

• External Fertilisation : Fusion takes place outside the female body.

Examples : Frog, fish, etc.

Answer 2

$\Huge{\sf Fertilization \colon}$

• Organisms of the Class Pisces,Amphibia and Reptilia lay their eggs in some sort of a medium

• The medium is water incase of amphibians

• The male gametes fuse with the egg cell in the media,i.e,outside the female organisms' body

• This type of fertilization is known as External Fertilization

• There is a disadvantage though,as the gametes can be eaten away by other organisms

• Improper development could be another problem,if the zygote isn't provided necessary conditions to hatch, then it would die
