Parts of Seaweed

  • Holdfasts- like roots, anchor the plant
  • Stipe- like a stem, absorbs shock
  • Blade- the big leaf of the plant
  • Bladelets- small blades
  • Air Bladders- pockets of air for buoyancy, so the plant can get closer to the sun for photosynthesis
  • Thallus- the entire plant
