WebThe 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). WebThe female and male inflorescence of the pine tree develop as cones on the sporophyte. The female cones (female strobili, singular strobilus) consist of megasporophylls that carry uncovered (Gymno = naked / exposed, hence Gymnosperms) ovules. Inside the ovule the megasporocyte undergoes meiosis, producing four haploid cells.
