Dive into the fascinating world of marine algae, the autotrophs of the sea that play a crucial role in marine ecosystems and the global environment. Often referred to as seaweed, algae come in a mesmerizing array of colors - red, green, and brown. These photosynthetic organisms are the unsung heroes of the ocean, forming the foundation of the marine food web and producing much of the oxygen we breathe. However, when conditions are just right, algae can multiply rapidly, leading to harmful outcomes. In the course, we’ll learn to differentiate between macroalgae and identify the unique characteristics of red, green, and brown. We’ll examine anatomy as we recognize the holdfast, stipe, blades, and bladders that make up their structures. Join us to discover algae's vital ecological roles, from providing sustenance for marine life to offering protection and camouflage.
