Embryogenesis is a developmental process that usually begins once the egg has been fertilised.
Explanation:
The fertilisation of the egg cell and the sperm cell results in the formation of a single celled zygote. On undergoing mitotic divisions ( cleavage) the zygote further develops into a multicellular embryo.
In plants, the embryo ( along with other cells from the plant ) develops into the seed that germinates as a new plant. The zygotic embryo is formed following double fertilisation of the ovule. Embryogenesis involves cell growth and division, cell differentiation and programmed cell death.
