Seaweeds or Macroalgae are the large primary producers of the sea. Though more complex than the unicellular algae, seaweeds still lack the complex structures.

Life History Chapter 6. Reproduction Complex in seaweeds Asexual or vegetative reproduction is common Fragments of thallus can often grow into new individuals.
