Cellular morphogenesis in land plants and brown algae is typically a slow process involving growth established by an interplay of turgor pressure cell wall rigidity. However, recent study showed that zygotes the alga Dictyota dichotoma undergo rapid shape change from sphere to elongated spheroid about 90 s, establishing first body axis.
