Fertilized egg
Fertilized Egg
A fertilized egg, also known as a zygote, is the initial stage of development in sexually reproducing organisms. This occurs when a sperm from a male unites with an ovum (or egg) from a female during the process of fertilization.
Formation[edit | edit source]
The formation of a fertilized egg begins with the process of sexual reproduction. This involves the fusion of male and female gametes (sperm and ovum respectively) in a process known as fertilization. The sperm and ovum each carry half the genetic material required to form a new individual. When they unite, they form a single cell called a zygote, which contains all the genetic information necessary to form a new individual.
Development[edit | edit source]
Following fertilization, the zygote begins to divide and grow in a process known as cell division. This involves the replication of the zygote's DNA and its division into two new cells. These cells continue to divide and differentiate into various cell types, eventually forming a complex multicellular organism.
Role in Reproduction[edit | edit source]
The fertilized egg plays a crucial role in sexual reproduction. It is the first step in the formation of a new individual, carrying all the genetic information necessary for the development of a new organism. The fertilized egg also initiates the process of embryonic development, which involves the growth and differentiation of cells to form a new organism.
