A type of sexual reproduction where sperm are small and motile, and eggs are large and non-motile.
Fusion of motile sperm and non-motile egg; occurs in some chytridiomycetes, not in any fungal plant pathogens.
reproduction in which the female gamete is large and non-motile and the male gamete small and motile.
Sexual reproduction involving the fusion of a small, flagellated male gamete with a larger, nonflagellated female gamete
A condition in which male and female gametes differ, such that a small, flagellated sperm fertilizes a large, nonmotile egg.
A type of heterogamy in which plasmogamy takes place between a large nonmotile egg and a small motile male gamete or cytoplasm from an antheridium. ( 15)
Oogamy is a form of heterogamy in which the female produced gamete is significantly larger than the male gamete. Highly motile sperm participate in the fertilization of the immotile egg. The opposite of this is isogamy, where gametes from both sexes are of similar size.
