NEET BIOLOGY

Detailed explanation-1: -Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. In many instances, the embryo is isolated within the female, which limits predation on the young. Internal fertilization also increases the likelihood of fertilization by a specific male.

Detailed explanation-2: -This pollen tube carries a male gamete to meet a female gamete in an ovule. In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower.

Detailed explanation-3: -Internal fertilization is the union of an egg and sperm cell during sexual reproduction inside the female body. Internal fertilization, unlike its counterpart, external fertilization, brings more control to the female with reproduction.

Detailed explanation-4: -Internal fertilization is characterized by sperm fertilizing the egg within the female; the three methods include: oviparity (egg laid outside female body), ovoviparity (egg held within female), and viviparity (development within female followed by live birth).
