Question

In angiosperms, sometimes it is seen that an embryo maybe formed from the deploid cells of the nucellus. It is a case of _________________

• A. Apospory
• B. Parthenocarpy
• C. Parthenogenesis
• D. Polyembryoniy

Answer 1

Answer:

D. Polyembryoniy

• Polyembryony is a phenomenon where multiple embryos develop from the nucellus or other tissues of the ovule, rather than from the fertilized egg cell.

• This can occur in some angiosperms, and it's a type of apomixis.

- Apospory: formation of sporophytes from somatic cells without meiosis.

- Parthenocarpy: development of fruit without fertilization.

- Parthenogenesis: development of an embryo from an unfertilized egg cell.
