General Characteristics of plants....
  • Cells?
  • Description?
  • Where they are found?
  • How they eat?
  • Multicellular eukaryotes
  • Complex bodies with extensive specialization of cells
  • Mostly terrestrial
  • Photoautotrophs (almost all)
    • Exception: Monotropa Uniflora
Oldest evidence of plants dates back to...
~470 MYA
What group are plants most closely related to? What is he evidence of this close relationship? (4)
Answer 3
Green Algae (Charophycean algae)
  • Formation of a "phragmoplast" during cytokinesis
  • Plasmodesmata (distinctive intercellular connections)
  • Cellulose-rich cell walls
  • DNA sequence similarities
Without looking at the picture, go through the concept map naming all of the phylums in the following:
  • Non-vascular plants
  • Seedless plants
  • Seed plants
Answer 4
Hopefully you only looked here to check your work..
1st land plants
~470 MYA
First vascular plants
~400 MYA
First seed plants
~360 MYA
First flowering plants
~120 MYA
Challenges with living on land (4):
  • Desiccation-loss of water
  • Exposure to elevated UV radiation levels
  • Aerial parts not in direct contact with water/nutrients
  • Support for body
Adaptations with living on land (3):
  • Alternation of generations with multicellular embryo
  • Production of sporopollenin-walled spores inside of sporangia
  • Production of gametes inside a multiceulluar
There are 13 Phyla in the Kingdom Plantae. Organize and name what groups they break up into (4), and how many are in each group:
  1. Non-vascular plants (3)
  2. Seedless vascular plants (4)
  3. Seed-producing vascular plants (5)
  4. seed-and-fruit-producing flowering plants (1)
Non-vascular plants include:
  • Bryophytes
    • Examples:
      • Mosses
      • Liverworts
      • Hornworts
1st plant to land is believed to be:
Liverworts
Examples of Seedless Vascular Plants:
  • Lycophytes
  • Ferns
  • Horntails
  • Whisk Ferns
What do sporophytes produce?
Spores
