Some of the larger ones have complex structures with special tissues that provide support or transport nutrients and the products of photosynthesis; others are made up of cells that are all virtually identical. Most seaweeds grow on longlines suspended around 48 feet below the surface throughout the winter. Under normal conditions, photosynthesis is the dominant process, allowing the seaweeds to build up their carbohydrate content.

In sea lettuce (Ulva lactuca), the cells all undergo division more or less randomly throughout the organism. So although we may find its odor offensive, many scientists think that the DMS generated from the decomposition of marine algae, especially phytoplankton, plays a vital role in the regulation of the Earths climate.

When the seaweed can make the ocean water clean, then the marine animals that live in it will also be healthy. Konbu contains more than 1001,000 times as much iodine as nori.

However, when it comes to herbivorous animals in the sea, like some fish, we know much less about the role microbes play in helping to digest food. In both cases this is due to substances called bromophenols, which the seaweeds synthesize. Access to nitrogen is an important limiting factor in seaweed growth, particularly for green algae. The water drowns the roots of plants, and the salt poisons the plant's system. Because they contain a large volume of soluble and insoluble dietary fiber, which are either slightly, or else completely, indigestible, seaweeds also have a low calorie count.
