Porphyra Reproduction and Life History


    Now it's time to tackle Porphyra's life history! Porphyra's life history has been studied intensely throughout time, especially because of its high economic value. Originally, it was thought that Porphyra had a single life history stage, however, in 1949, Kathleen Drew-Baker discovered that the alga Conchocelis rosea was actually a stage in the life history of Porphyra! Therefore, Porphyra has a trimorphic life history, with a thallus stage, carposporophyte stage and a filamentous Conchocelis phase, as shown below.
