(iv) Brown Algae

Brown algae include the giants of the protist kingdom. All brown algae are multicellular and range
from a few centimeters to approximately 75 meters in length. The largest brown algae, called the
kelps are tough and leathery in appearance. They possess leaflike blades, stemlike stipes, and
rootlike anchoring holdfast. Brown algae are common in cooler marine waters, especially along
rocky coastlines in the intertidal zone (Fig. 7.11).
