Kingdom Plantae

  • Describe:
    • eukaryotic
    • perform photosynthesis
    • have chlorophyll 
    • cells walls made of cellulose
  • Body Plan:
    • muticellular
  • Divergent Event:
    • scientists believe land plants evolved from green algae
  • Metabolism:
    • autotrophic
  • Digestion:
    • none
  • Circulation:
    • only some plants have circulatory systems- vascular plants
    • no heart
  • Respiration:
    •  the chemical opposite of photosynthesis - it releases energy, using up food and oxygen and producing carbon dioxide
    • the release of energy from food
  • Nervous:
    • none
  • Reproduction:
    • both sexual and asexual
      • Sexual - roses 
      • asexual – maple tree
  • Examples:
    • Moss
    • Shrubs
Phylum Cycadophyta 
  • Describe
    • Dioecius
    • Tropical and sub-tropical habitats
    • Pachycaul stem
    • Girdling leaf traces
    • Coralloid roots
    • Lack axillary buds
    • Open carpophyll
    • Woody, long-lived, unisexual plants. Main roots thickened, fleshy, often tuberous
  • Environment -
    • Tropical and subtropical latitudes in the Americas, Caribbean, sub-Saharan Africa, Madagascar, eastern India, China, Japan, southeast Asia, Oceania and Australia.
  • Examples -
    • Cycas rumphii

    • evergreen

Phylum Gingkophyta

  • Describe -
    • distinctive fan shaped leaves & are dioecious (each tree is either male or female but not both)
  • Enviroment -
    •  not native to North America (they are found growing wild only in China)
  • Examples -
    • Ginkgo biloba tree
 Phylum Anthopyta
Class Monocotyledonae
  • Describe -
    • comprising seed plants that produce an embryo with a single cotyledon and parallel-veined leaves
    •  includes grasses and lilies and palms and orchids
    • divided into four subclasses or superorders: Alismatidae; Arecidae; Commelinidae; and Liliidae
  • Example -
    •  Hemerocallis flower


Class Dicotyledonae
  •  Describe -
    • comprising seed plants that produce an embryo with paired cotyledons and net-veined leaves
  •  Example
    •  beans
    • ground nut
