Vedclass · Answer

(B) In typical meiosis,a single spore mother cell (microspore mother cell or megaspore mother cell) undergoes division to produce a tetrad,which consists of four spores. When more than four spores are produced from a single spore mother cell,the phenomenon is known as Polyspory. Polyspermy refers to the fertilization of an egg by more than one sperm. Polyembryony is the development of more than one embryo in a single seed. Polysiphony is a term related to the thallus structure in certain algae.
