Where can Phaeophyta be found?
The group is found primarily in colder waters of the northern hemisphere, with the largest forms occurring in cooler waters, rather than in the tropics. Many familiar species, such as rockweed, are intertidal, and are exposed to the air at low tide.
What is Phaeophyta used for?
Their common uses include as food thickeners and fillers as well as stabilizers for the ionization process of batteries. According to some medical research, several chemicals found in brown algae can work as antioxidants, which are thought to prevent damage to the human body.
