Phycology

Phycology, also known as algology, is the sub-discipline of biology and botany focused on the scientific study of algae. This field investigates a vast and diverse group of photosynthetic organisms, from microscopic single-celled forms to large multicellular seaweeds like kelp, which are crucial primary producers in most aquatic ecosystems. Phycologists examine the taxonomy, life cycles, ecology, and physiology of these organisms, exploring their fundamental role in global oxygen production and their practical applications in biotechnology, food manufacturing, and the development of biofuels.
