Question

Give the significance of fertilisation.

Answer 1

1. Fertilisation ensures diploid of the organism by fusion of male and female gametes

2. It provides new genetic constitution to the zygote

3. It increases metabolic activities

Answer 2

Fertilization is the process that makes a cell capable of the cell division to form a complete organism.

Explanation:

• Fertilization insures the fusion of haploid male and female gametes that later starts the cell divisions i.e. fertilization starts the egg activation for the further cell division process.
• Zygote gets the new genetic constitution by the help of fertilization.
• The rate of protein synthesis is increased along with the metabolic activities of the egg by the process of fertilization.
