Summary Of: Alternation of generations

alternation of generations implies that both the diploid and haploid stages are multicellular and this is more important... Foraminifera undergo a heteromorphic alternation of generations between a haploid... Alternation of generations occurs in almost all marine...

Sporic or diplohaplontic life cycle. A diploid (2n) sporophyte undergoes meiosis to produce haploid (1n) reproductive cells, often called spores. Haploid cells undergo mitosis to produce a gametophyte. The gametophyte produces haploid gametes which fuse to form a diploid zygotic sporophyte. | | zygotic | plants | fungi | protists | diploid | haploid | generation | species | life cycle | gametophyte | thallus (tissue) | haploid | sporophyte | diploid | mitosis | combine | zygote | meiosis | sexual reproduction | Ulva lactuca | gymnosperms | angiosperms | embryophytes | bryophytes | plants | multicellular | pollen | ovules | parthenogenic | sexually reproductive | mycelia | multinucleate | heterokaryon | plasmogamy | diploid | karyogamy | foraminifera | plasmodium | algae | red algae | green algae | brown algae | Kelp | brown alga | Laminaria | Bryophyte | liverworts | hornworts | mosses | gametangia | archegonium | antheridium | meiosis | sporangia | | | | Ferns | clubmoss | horsetails | meiosis | spores | wind | water | prothallus | zygote | | | | | archegonium | pollen | zygote | Evolutionary history of plants#phases | ISBN 0-521-38294-7 | Proceedings of the National Academy of Sciences | doi | v | d | Botany | Ethnobotany | Paleobotany | Plant anatomy | Plant ecology | Plant evo-devo | Plant morphology | Plant physiology | | Plants | Evolutionary history of plants | Algae | Bryophyte | Pteridophyte | Gymnosperm | Angiosperm | Flower | Fruit | Leaf | Meristem | Root | Stem | Stoma | Vascular tissue | Wood | Plant cells | Cell wall | Chlorophyll | Chloroplast | Photosynthesis | Plant hormone | Plastid | Transpiration | Gametophyte | Plant sexuality | Pollen | Pollination | Seed | Spore | Sporophyte | Plant taxonomy | Botanical name | Botanical nomenclature | Herbarium | IAPT | ICBN | Species Plantarum | Category | Portal | Categories | Plant reproduction | Reproduction |
