You have seen three of these four outside today. We group these four based on the characteristics listed from their ID cards. I will give you one group in class. You need to figure out the others and put them in proper order of simplest to most advanced plant groups. GROUP ONE NAME: ______________________________________________________________ Vascular Tissue: _________________ Seeds/Spores: _________________ Flowers: _________________ What plants did you see that are examples of this group? : GROUP TWO NAME: ______________________________________________________________ Vascular Tissue: _________________ Seeds/Spores: _________________ Flowers: _________________ What plants did you see that are examples of this group? : GROUP THREE NAME: ______________________________________________________________ Vascular Tissue: _________________ Seeds/Spores: _________________ Flowers: _________________ What plants did you see that are examples of this group? : GROUP FOUR NAME: Vascular Tissue: Seeds/Spores: Flowers: ______________________________________________________________ _________________ _________________ _________________ What plants did you see that are examples of this group? : TREE A Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE B Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE C Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE D Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE E Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE F Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE G Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE H Vascular Tissue: NO Seeds or Spores: SPORES Flowers: NO TREE I Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE J Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE K Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE L Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES TREE M Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: NO TREE N Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: NO TREE O Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: NO TREE P Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: NO ANGIOSPERMS Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: YES Example: Flowering Dogwood Trees GYMNOSPERMS Vascular Tissue: YES Seeds or Spores: SEEDS Flowers: NO Example: Pine Trees SEEDLESS, VASCULAR Vascular Tissue: YES Seeds or Spores: SPORES Flowers: NO Example: Ferns NONVASCULAR Vascular Tissue: NO Seeds or Spores: SPORES Flowers: NO Example: Mosses
