Kingdom Plantae: Sporic life cycle (“meiosis produces spores)
Be able to identify GAMETOPHYTE and SPOROPHYTE.
o Gametophyte = “plant that produces gametes” (haploid) [gametes produced by
mitosis]
o Sporophyte = “plant that produces spores” (diploid) [spores produced by meiosis]
Read introduction (pg. 221).
17. 1 Life Cycle of Seed Plants
