  2. What is a Plant? • Autotrophs • Multicellular • Cell Structure Adaptations for Living on Land 1) Obtaining ____________ & other nutrients 2) Retaining _________ • CUTICLE: waterproof coating on leaves 3) Transporting Materials • _______________ tissue: system of tubes 4) Support • Cell walls: are __________ enough to support the plant 5) Reproduction Section 1: THE PLANT KINGDOM

  3. CLASSIFICATION OF PLANTS • Nonvascular – low-growing and simple • Vascular – have vascular tissue! • Where do plants come from? • Green __________ • Green pigment called ________________ COMPLEX LIFE CYCLES • Sporophyte Stage  spores • Gametophyte Stage  fertilization (zygote)
