Accepted Answer

Correct Answer: A &mdash; ParthenogenesisParthenogenesis is the development of an embryo from an unfertilised female gamete (egg). In plants, this is a form of apomixis where the egg cell develops into an embryo without the fusion of male and female gametes. Examples include some varieties of citrus, grapes, and dandelions.Other terms:Autogamy (B): Self-pollination within the same flower; transfer of pollen from the anther to the stigma of the same flower.Parthenocarpy (C): Development of fruit without fertilization; the fruit is seedless (e.g., banana). This involves the ovary wall developing into a fruit in the absence of fertilization, but no embryo is formed.Syngamy (D): The fusion of male and female gametes (fertilization proper); the opposite of parthenogenesis.Key Concept: Parthenogenesis = embryo development from unfertilised egg (no fertilization required). It differs from parthenocarpy, which is fruit development without fertilization (no seeds formed). Both are types of agamospermy/apomixis in plants.
