Question

Development of an embryo from an unfertilized egg cell is called as

• A. Apogamy
• B. Apospory
• C. Apomixis
• D. Parthenogenesis

Hint:

Parthenogenesis = "virgin birth".
Apomixis is the general asexual seed formation, while apogamy/aposory are specific forms.
Focus on origin: egg cell → embryo → parthenogenesis.

Answer 1

The Correct Option is D

Parthenogenesis is the development of an embryo from an unfertilized egg cell without fertilization. Apomixis is a broader term for asexual reproduction in plants, which may include parthenogenesis or apogamy. Apogamy refers to embryo development from sporophytic tissue, and apospory is embryo formation from gametophytic tissue. Here, the direct development from egg cell fits parthenogenesis.
