Vedclass · Answer

(B) During the process of double fertilization in angiosperms,the pollen tube enters one of the synergids through the filiform apparatus.Upon entering the synergid,the pollen tube ruptures and releases two male gametes into the cytoplasm of that synergid.One male gamete fuses with the egg cell to form a zygote (syngamy),and the other male gamete fuses with the two polar nuclei to form the primary endosperm nucleus (triple fusion).Therefore,the correct sequence is that the pollen tube enters one synergid and releases two male gametes.

In double fertilization,after entering ..... of the synergids,the pollen tube releases ..... male gametes into the cytoplasm of the synergids.
