BIOL 142: Study Guide for TEST # 3 Chapter 30 – Green Plants Defining characteristics of land plants : protected from dessication by a waxy cuticle , use stomata for gas exchange, leaves increase area for photosynthesis , protected embryos, and life cycles with alternation of generations (multicellular haploid and diploid stages), the diploid stage becomes more dominant in more advanced plants Classification: Green Plants = Kingdom (Viridi)plantae = green algae + land plants (common ancestor about 1 BYA) - Green algae are divided into 2 groups ( chlorophytes and charophytes )- Bryophytes are nonvascular land plants (= mosses) with a dominant gametopyte generation- Vascular plants include pterophytes (= ferns - have fronds with sori and water is required for fertilization), and seeded plants ( gymnosperms and angiosperms )- Gymnosperms = reproduce with male and female cones and ‘naked seeds’ – include conifers (pines, etc.), cycads, gnetophytes, and ginkgos- Angiosperms = flowering plants
