Question

Which mechanism involves the splitting or division of the zygote or proembryo into multiple parts?

Options

• Cleavage Polyembryony

• Multiple Embryo Sac Formation

• Adventive (Nucellar) Polyembryony

• Sporophytic Cell Activation

Answer 1

Cleavage polyembryony is the mechanism by which the zygote or proembryo splits (cleaves) into parts, with each part developing into an independent embryo. This mechanism is observed in plants such as Nymphaea, Adansia, and various Orchids, representing a form of asexual reproduction derived from the fertilised egg.
