The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy). The union of male and female gametes to form a zygote. A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. A process, occurring at the cellular level, that is involved in the reproductive function of a multicellular or single-celled organism. The directed movement of substances into, out of or within a cell by a cellular process that begins with the formation of membrane-bounded vesicles in which the transported substances are enclosed or located in the vesicle membrane. Vesicles are then targeted to, and fuse with, an acceptor membrane. Penetration of the egg shell through the micropyle (a specialized anterior opening in the vitelline envelope) and entry of the entire sperm, including the surrounding plasma membrane and the sperm tail, into the egg cytoplasm. This step in fertilization is seen in Drosophila, where a plasma membrane fusion event between the sperm and the egg does not occur. The infolding of a membrane, resulting in formation of a vesicle. A type of vesicle-mediated transport in which cells take up external materials or membrane constituents by the invagination of small region of the plasma membrane to form a new membrane-bounded vesicle.
