Question

The phenomenon of embryo formation from a vegetative cell derived from zygote is known as

• A. Aposporay
• B. Diploid polyembryony
• C. Adventitive polyembryony
• D. Apomixis

Answer 1

The correct option is C Adventitive polyembryony

•Apospory is the formation of gametophyte from the sporophytic cells without the formation of spores.

•Adventive Polyembryony is a type of Apomixis in which there is formation of embryo due to sporophytic budding. One or more diploid sporophytic cells, either nucellus or integuments undergo stages of embryogeny and eventually develop into mature embryos.

•Apomixis is a kind of asexual reproduction in which viable embryo is formed within the confines of the seed coat, without meiosis and syngamy. Hence, embryo formation from a vegetative cell derived from zygote is known as Adventive Polyembryony because zygote will form the sporophytic plant body and any sporophytic cell may undergo stages of embryogeny to form the embryo.

So, the correct answer is C.
