1. Seaweeds, also known as macroalgae, comprise a diverse group of organisms representing various growth forms.

2. Seaweed comes in 3 colors green, brown, and red ( but colors within these groups vary)

3.  seaweeds lack the complex reproductive structure found in sea grass and land plants

4. Most seaweed attaches to hard surfaces such as rocks, shells or other algae, using a specialized basal structure called a holdfast; however, a few seaweed species survive over mud or sandy bottoms.

5. Seaweed is autotrophic, which means it produces its own food; using sunlight, macroalgae convert carbon dioxide and water into oxygen and sugar (photosynthesis).

I hope this helps you.
