Edible algae, also known as seaweed or macroalgae, are aquatic plants that are consumed as food by humans and animals. They have been a staple in many cultures for centuries, particularly in East Asian cuisines like Japanese, Chinese, and Korean. Here is all about edible algae.
What are algae?
Algae are a diverse group of photosynthetic organisms that are found in all types of aquatic environments, as well as in moist soil and on rocks. They are not a single taxonomic group, but rather a polyphyletic grouping, meaning that they do not share a common ancestor.
Algae can be either unicellular or multicellular, and they range in size from microscopic single-celled organisms to giant kelps that can grow up to 200 feet long. They have a variety of shapes and colours, and their photosynthetic pigments can be green, blue-green, red, brown, or yellow.
