D E A B C Receptacles :Contain male or female conceptacle :Reproductive system Air bladder :Floating Heterokontophyta Blade- use the sun's energy for photosynthesis and reproductive system Holdfast- keeps algae in place so currents and tides don't wash the organism away. Phylum __________________ Class __________________ Genus __________________ Fucus Heterokontophyta Phaeophyceae Stipe- support the algae

they do not perform nutrient transport “Stipes of kelps look like the stems of plants, but they do not perform nutrient transport functions like the stems of plants. Their main function is to provide support for the blades. Sorry! I,Kim, was wrong!! Designed by Pyeongsug Kim, ©2009
