Document Summary

Large haploid gametothallus is most prominent- heteromorphic alternation of generation porphyra. Antheridium (m) produces spermatia, which are male ga(cid:373)etes that do(cid:374)"t ha(cid:448)e flagella. Now diploid carpegonium is complex, internal single cell large trichogyne, sticking out, where spermatia attach to fertilize carpegonium (egg: 1st: carpsporothallus, surrounded by pericarp (cup like), it is haploid! Inside, produce carpospores, diploid, and released to settle on another surface: carpospores and gametophyte are heteromorphic, alteration of generation (move through cycle, mixed, next stage is isomorphic, after attaches, forms tetrasporothallus-isomorphic, carposporophyte will produce diploid carpospores- heteromorphic.
