Document Summary
Gametophyte: haploid, multicellular, produce gametes by mitosis. Zygote: diploid, single cell, develops by mitosis into the sporophyte generation. Spore: haploid, single cell, develops into a gametophyte by mitosis. Sporophyte: diploid, multicellular, produces spores through meiosis. Gamete: haploid, single cell, fuses with another cell to produce a zygote. What is something that is not true about lycophytes and pteridophytes: lycophytes and pteridophytes have seeds. T/f selaginella produce two types of spores: true. What group do liverworts and mosses belong to: bryophytes. In ferns spores germinate and become : gametophytes. Why does a population of organisms have to produce more offspring than will survive to reproduce: there has to be competition for resources for the laws of natural selection to apply. Not an example of artificial selection: the beaks of the birds on the galapagos islands. In gymnosperms how is pollen distributed: wind. T/f pollen grains are multicellular male gametophytes: true, not sperm. T/f pollen is the same as sperm: false.
