Algae are aquatic organisms belonging to the kingdom Protista and are found in marine and freshwater environments. Although often mistaken for plants, algae lack true roots, stems, or leaves.
They come in a wide variety of shapes and colors, ranging from microscopic to large seaweeds.
Algae are important for the ecosystem as they produce oxygen through photosynthesis and are the foundation of the aquatic food chain. Additionally, they are used in the food industry, cosmetics, and scientific research.
