Zygote
embryo
A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The zygote stage development occurs in the first week of fertilization
Embryology is a science which is about the development of an embryo from the fertilization of the ovum to the fetus stage.
When the sperm meets the ovum and goes into the zygote .
The first process in the development of a human being is fertilization, where a sperm cell fertilizes an egg cell to form a zygote. This marks the beginning of a new individual and sets off a series of developmental processes leading to the formation of a complete human organism.
First Stage: The first two weeks after conception are known as the Germinal stage. Second Stage: The next six weeks of development are known as the Embryonic stage. Third Stage: The remainder of prenatal development is known as the Fetal stage.
The cumulus/development stage
The Cumulus Stage
The Cumulus stage
An organism at an early stage of its development is referred to as an embryo. During this stage, the organism undergoes rapid cell division and differentiation to form various tissue layers and organs. The embryo is crucial for the development of the organism into its final form.
The correct order of the stages in development is typically: 1) germinal stage, 2) embryonic stage, and 3) fetal stage. These stages represent the progression from fertilization of the egg to the formation and growth of the fetus in the womb.
The kind of fertilization and development that takes place in aquatic animals is known as External fertilization.
