WebLife Cycle. Porphyra displays a heteromorphic alternation of generations. The thallus we see is the haploid generation; it can reproduce asexually by forming spores which grow to … WebThe complete life-cycle of Porphyra was now known. This discovery renewed interest in the biology of Porphyra, especially the conditions for growth (Iwasaki and Matsudaira, 1958) and production of monospores (Kurogi and Hirano, 1956). 1Present Address: Tohoku University, Faculty of Agriculture, Department of Fisheries, Sendai, Japan. 173 how do i change game mode minecraft
