Cleavage polyembryony occurs in
Cleavage polyembryony occurs in
Open in App
Solution
The correct option is A Pinus
Cycas exhibits simple polyembryony, wherein fertilization of more than one archegonia results in the formation of multiple embryos.Pinus exhibits cleavage polyembryony, wherein separation of embryonal cells is followed by the development of each of them into potential embryos. Thus, four embryos are formed by single fertilized egg owing to the separation of embryonal cells. Ephedra exhibits modified cleavage polyembryony, wherein precocious division in zygote results in the formation of eight daughter cells each of which serves as a potential embryo. Thus, the correct answer is option A.
