We can compare their output with that of plants by looking at the amount of organic carbon generated per square meter on an annual basis. The seaweed cells make use of several types of starch-like carbohydrates for internal energy storage; again, these vary according to species. It is highly nutritious. Finally, after nine years worth of effort to grow the alga in light- and temperature-controlled tanks, she discovered that the spores would germinate if they were allowed to settle on a sterilized oyster shell. Most species of seaweeds have soft tissues but some are, to a greater or lesser degree, calcified, an example being calcareous red algae. 3.
