Plant Characteristics

Plant CharacteristicsVocabulary1. Alternation of GenerationsA haploid plant (gametophyte) and a diploid plant (sporophyte) alternate to complete a plants life cycle.5. Diploid(2N). A cell with two copies of each chromosome. The sporophyte generation and spores are diploid.14. Haploid(1N). A cell with only 1 copy of each chromosome. The gametophyte generation and gametes are haploid.16. MeiosisCell reproductive process that yields four genetically unique haploid cells.18. MitosisCell reproductive process that yields two genetically identical copies of cells.11. GameteEgg or sperm. Haploid.25. SporeA haploid cell that grows into the gametophyte.

8. FertilizationThe fusing of a haploid egg and haploid sperm to produce a unique diploid zygote/embryo.29. ZygoteThe single diploid cell resulting from the fertilization of an egg cell by a sperm cell.6. EmbryoThe diploid result of fertilization of two gametes. Develops into the sporophyte.12. GametophyteThe haploid generation in a plants life cycle that produces gametes.10. GametangiumTissue in gametophyte that produces gametes.27. SporophyteThe diploid generation in a plants life cycle that produces haploid spores.24. SporangiumTissue in sporophyte that produces spore cells3. BryophyteMosses, liverworts and hornworts. Gametophyte is dominant generation. Sporophyte often dependent on gametophyte. No vascular system, leaves or roots. Spread by spores. Relies on water for sperm to travel.

22. RhizoidThe root-like supportive structures of moss and other non-vascular plants.7. Fern (and fern allies)Have vascular system, true roots, leaves (called fronds) and stems. Sporophyte and gametophyte generations live independently. Spread by spores. Relies on water for sperm to travel.9. FrondFern leaf that starts as a fiddlehead. Often have sporangia on back.13. GymnospermPines, cycad, ginkgo. Gametophyte generation is tiny and lives within the cone. Pollen travels by wind. Embryo contained in a seed. 21. PollenHouses male gametophyte that produces sperm in seed plants.23. SeedGymnosperm and angiosperm structure for dispersal. Contains an embryo, stored food and a seed coat.2. AngiospermFlowering plant. Gametophyte tiny and lives in the flower of a sporophyte. Produce seeds surrounded by fruit. Often pollinated and dispersed by animals.4. CarpelThe female part of a flower (all the carpels together make a pistil). Contains an ovary with the gametophyte that produces egg cells.19. OvaryThe female reproductive organ of angiosperms where eggs develop. Becomes the fruit surrounding the seeds.28. StamenThe male reproductive structure of angiosperms that produce pollen.20. PhotosynthesisThe process by which plants convert carbon dioxide and water into glucose and oxygen. Captures the suns energy making it available to all life.
