Etymology
The term 'microalgae' is derived from two components: the prefix 'micro-' which comes from the Greek word 'mikros' meaning 'small', and 'algae', which originates from the Latin word 'alga', meaning 'seaweed' or 'marine plant'. The study of microalgae began in earnest in the 19th century with advancements in microscopy that allowed scientists to explore these tiny organisms. Over time, their importance in ecological systems became increasingly recognized, especially their role in aquatic food webs and oxygen production. Today, microalgae are being researched for their potential in addressing global challenges such as climate change, food security, and renewable energy production. Their diverse applications in biotechnology, pharmaceuticals, and nutrition underscore their significance in both scientific research and industrial applications.
