The correct sequence of embryonic development is :
The correct sequence of embryonic development is :
Open in App
Solution
The correct option is C Zygote - Morula - Blastula - Gastrula - Embryo
Following fertilisation, the mitotic division starts as the zygote moves towards the isthmus of the oviduct towards the uters. This is called cleavage. The cleavage converts the egg into a compact mass of blastomeres called morula, which ultimately transforms into blastula by continuous divisions . The blastula precedes the formation of the gastrula, in which the germ layers of the embryo forms.
Gastrulation is followed by organogenesis when individual organs develop witinin the newly formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo thus, the correct sequence is Zygote --> Morula --> Blastula --> Gastrula --> Embryo
