Quick Summary

A macrophyte is a member of the macroscopic plant life, particularly those found in bodies of water. These plants are visible to the naked eye, distinguishing them from microscopic aquatic life.1

An example of a macrophyte is Macrocystis, commonly known as giant kelp. These brown algae can form vast underwater forests, providing essential habitats for marine creatures. The largest species, M. pyrifera, can grow up to 65 meters (215 feet) long and is known for its rapid growth rate. Giant kelps have a root-like structure called a holdfast for anchoring, a stipe for internal transport, and gas-filled bladders that help their blades float. They are commercially harvested for alginate, a substance used in various industries.2
