Vedclass · Answer

(A) The development of an embryo from any cell of the embryo sac other than the egg cell (such as synergids or antipodal cells) is known as $Apogamy$. In this process, the haploid cells of the embryo sac give rise to the embryo without fertilization. $Apospory$ refers to the development of a diploid embryo sac from a vegetative cell of the nucellus. $Adventive$ $	ext{embryony}$ involves the development of an embryo directly from diploid sporophytic cells like the nucellus or integuments. $Diplospory$ is a type of apomixis where the embryo sac develops from a diploid megaspore mother cell.
