Most of the approximately 1,500 species of Mastigophora are propelled by one or more flagella, and members of the group are sometimes referred to as flagellates. Some have pseudopodia, temporary armlike protrusions of cytoplasm that help the cell move about and enwrap particles of food. Asexual reproduction by binary fission is the norm, but some species reproduce sexually by a process called syngamy, the fusion of two gametes produced by meiosis meiosis , process of nuclear division in a living cell by which the number of chromosomes is reduced to half the original number. Meiosis occurs only in the process of gametogenesis, i.e., when the gametes, or sex cells (ovum and sperm), are being formed.
