... , nonsexual phase is the sporophyte. In the gametophyte phase, male and female organs (gametangia) develop and produce eggs and sperm (gametes), which unite in fertilization (syngamy). The fertilized egg (zygote) develops into the sporophyte, which produces numerous single-celled spores, which in turn develop directly into new gametes.

... stage, fertilization is by syngamy, that is, the union of male and female gametes. All Sporozoa are parasitic. The subphylum is divided into three classes—Telosporea, Toxoplasmea, and Haplosporea. See Haplosporea, Protozoa

... sexually by a process called syngamy, the fusion of two gametes produced by meiosis (i.e., fertilization).Some parasitic members of the Mastigophora are the causative organisms of disease in humans and other animals. Trypanosomes, for example, are the cause of African sleeping sickness and Chagas' disease, and giardiasis is caused by the mastigophoran Giardia ...

... . Sexuality, if present, is syngamy, the fusion of two gametes. Spores typically are not formed. Flagella may be permanent or transient or confined to a certain stage in the life history; this is true also of pseudopodia. Both flagella and pseudopodia may be present at the same time.Three superclasses are included: (1) Mastigophora, commonly flagellates, contains ...
