dinoflagellata life cycle: 1-binary fission, 2-sexual reproduction, 3-planozygote, 4-hypnozygote, 5-planomeiocyte


dinoflagellates have haplontic life cycle, possible exception of noctiluca , relatives.


the life cycle involves asexual reproduction means of binary fission, either through desmoschisis or eleuteroschisis. more complex life cycles occur, more particularly parasitic dinoflagellates. sexual reproduction occurs, though mode of reproduction known in small percentage of dinoflagellates. takes place fusion of 2 individuals form zygote, may remain mobile in typical dinoflagellate fashion , called planozygote. zygote may later form resting stage or hypnozygote, called dinoflagellate cyst or dinocyst. after (or before) germination of cyst, hatchling undergoes meiosis produce new haploid cells.
