efficient. Fertilization takes place when two gametes contact one another. The plasma membranes fuse to form a binucleate cell with nuclear fusion quickly following. The resulting zygote is initially biflagellate, but it soon encysts and germinates. It grows into a dichotomously branched sporophyte, which forms two types of sporangia: thin-walled zoosporangia that may be colorless or orange and thick-walled resting sporangia that are reddish-brown due to the presence of melanin pigments. The thin-walled zoosporangia give rise to motile zoospores that germinate and grow into another sporophyte. The resting sporangia undergo

called sirenin that attracts the male gametes. Male gametes produce a pheromone called parisin. Female gametes are sluggish and stay close to the female gametangia, which sets up a strong concentration gradient of sirenin. Fertilization of female gametes by male gametes appears to be near 100%

thalli consist of a cylindrical trunk-like basal cell that gives rise to well-developed, highly branched rhizoids that anchor the thallus to the substrate. The trunk-like basal cell also gives rise to numerous dichotomously branched side branches that terminate as either resistant sporangia,

life cycle the resting sporangia (from the sporophyte) give rise to biflagellated, bi-nucleated zoospores that will encyst, undergo meiosis, and germinate to yield motile gametes. These gametes will then fuse in pairs and the resulting zygotes germinate and grow into new sporophytes.
314:. In this life cycle, the two stages are indistinguishable until reproductive organs are formed. Gametophytes produce colorless female gametangia and orange male gametangia; the orange coloration is transferred to the male gametes and is due to the presence of gamma
