WitrynaThe male and female gametophytes of peas eventually engage in mating interactions to achieve fertilization (Friedman and Williams 2004; Zhong et al. 2024). The synergid cell of the female gametophyte is reported in some species to release a chemical signal that attracts the male gametophyte’s pollen tube to grow toward it (Isogai et al. 2015).

WitrynaCorrect option is C) The pollen grain is the male gametophyte which contains the male gametes. The pollen grain is surrounded by two layers as exine which forms the outer layer and intine which forms the inner layer. The generative cell divides to form the two male gametes. The intine layer comes out of the germ pore to form the pollen tube. WitrynaThe male gametophyte phase of the life cycle begins in the microsporangium with meiotic production of tetrads of microspores followed by the division of each haploid microspore into a three-celled pollen grain. Because it is multicellular, the pollen grain is considered to be an immature male gametophyte, but its further development into a ...
