Flagella only in gametes
WebZoid. Not to be confused with zooid. In botany, a zoid or zoïd / ˈzoʊ.ɪd / is a reproductive cell that possesses one or more flagella, and is capable of independent movement. [1] Zoid can refer to either an asexually reproductive spore or a sexually reproductive gamete. In sexually reproductive gametes, zoids can be either male or female ... WebThe gametes are produced from diploid germ cells, a special cell line that only produces gametes. Once the haploid gametes are formed, they lose the ability to divide again. There is no multicellular haploid life stage. Fertilization occurs with the fusion of two gametes, usually from different individuals, restoring the diploid state (Figure 7 ...
