Algae are a diverse group of predominantly aquatic, photosynthetic organisms ranging from microscopic species to large seaweeds. They play a crucial role in ecosystems by producing oxygen and serving as the base of aquatic food webs. Algae are utilized in various industries, including food, pharmaceuticals, and biofuel production.
Bioluminescence is the emission of light by living organisms resulting from a chemical reaction involving luciferin and luciferase. This phenomenon is widespread among marine species, including bacteria, algae, jellyfish, and fish, and also occurs in terrestrial organisms like fireflies and certain fungi.
Microbiology is the scientific study of microorganisms, including bacteria, viruses, fungi, protozoa, and algae, focusing on their structure, function, genetics, and interactions with their environments.
