Vedclass · Answer

(A) : In $60\%$ of flowering plants,the pollen grains are shed at the two-celled stage (tube cell + generative cell). Further development of the male gametophyte (pollen grain) occurs on the stigma. The pollen grain gives rise to a pollen tube,which absorbs nourishment from the cells of the style for its growth. The generative cell divides to give rise to two male gametes. Out of these,one fuses with the egg to form a diploid zygote (syngamy),whereas the second male gamete fuses with the two polar nuclei or the diploid secondary nucleus of the central cell to form the primary endosperm nucleus (triple fusion). These two acts of fertilization occur in the same embryo sac and are collectively referred to as double fertilization. Therefore,the statement that double fertilization does not take place when pollen is shed at the two-celled stage is incorrect.
