Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub

The formation of an embryo from any cell of the embryosac except the gamete or the origin of the embryo from either synergids or antipodal cells of the embryosac is called as apogamy. Both apogamy and apospory are sometimes described as abnormalities in the life cycle of a plant. It is commonly assumed that if one of these phenomena occurs in a life cycle, it must be followed by the other one. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes (notably ferns), the term is still used interchangeably with "apomixis", and both refer to the formation of sporophytes by parthenogenesis of gametophyte cells.
