Fundamental Biology

• Seeded, Vascular Plants are
• Multicellular
• Gain their energy from photosynthesis
• Collect nutrients through their roots and
  exchange gases through their stomata
• Reproduce sexually with the gametophyte totally
  dependent on the dominate sporophyte

3
Shared Features with Related Taxa

• Seeded Vascular Plants share
• chlorophyll b, storage of energy as starch,
  similar RNA and DNA, and cell walls made of
  cellulose with Charophytes, which are a type of
  green algae
• a waxy cuticle over their epidermal layer and
  stomata with nonvascular plants
• xylem and phloem transport tissue with vascular
  plants

4
Unique Features

• specialized sites of gamete production called
  gametangia
• seeds that are protected from drying
• flowers and fruit in the case of angiosperms

5
Importance

• Plants form the basis for most terrestrial food
  chains
• Convert carbon dioxide into oxygen
• Fossilized and extant plants are burned to
  provide electricity
• Many homes and other products are built out of
  wood
• Drugs such as aspirin, morphine, quinine, taxol,
  estrogen replacements, heart medications, and an
  antidote to cyanide poisoning are derived from
  plants
• Used in human mating rituals
• Chocolate and Caffeine!!!!!!

Fun Facts

• There is a housing insulation that blocks the
  vast majority of allergens that is nontoxic and
  made from soybeans.
• Even the barest shade blocks 80 of the suns
  heat
• There is a small tree that inhabits the
  understory of a rainforest in Cameroon that has a
  mutual relationship with ants , providing them
  with nectar and places to live in exchange for
  defense from herbivores such as caterpillars
• Phytroremediationis currently being used by the
  Environmental Protection Agency to clean up
  Superfund sites and occurs when toxins taken up
  by roots of plants are either released as a gas
  and removed from the soil or stored in the plant
  where they can be harvested and disposed of.
• Old growth forests get their nitrogen from
  Lobaria oregana lichen, which begin to grow in a
  forest after about a hundred years or so, fixing
  up to twenty-two pounds of nitrogen per acre each
  year.
