Also known as algal, algæ
Algae ( , ; : alga ) are any of a large and diverse group of photosynthetic organisms. It excludes the land plants (embryophytes). Such organisms range from microscopic unicellular microalgae (including cyanobacteria and phytoplankton) to seaweeds, multicellular macroalgae which may grow up to in length. Most algae are aquatic (especially marine), and some form cohesive colonies. Freshwater algae include Charophyta such as the filamentous Spirogyra and the grasslike stoneworts. Most algae are planktons carried passively by water, although some macroalgae have holdfasts for anchorage.
Algae are a diverse group of photosynthetic organisms that live mostly in water, ranging from microscopic single cells to large seaweeds that can grow many meters long. They play a fundamental role in aquatic ecosystems as primary producers, converting sunlight into energy that supports life in oceans and freshwater environments.

Alga (do latim: alga -e, "planta marinha") é o nome comum de um diversificado agrupamento polifilético de organismos fotossintéticos cujo ciclo de vida se completa geralmente em meio aquático, embora algumas espécies habitem no solo, sobre superfícies expostas à luz solar ou sejam fotobiontes em fungos liquenizados. A polifilia do grupo impede que a designação tenha valor taxonómico, embora tenha existido o ora obsoleto reino Algae L., 1751. Por não constituírem um grupo evolutivo único, mas o agrupamento de um conjunto alargado de organismo pertencentes a grupos filogenéticos muito diferentes, as algas são frequentemente definidas por padrão, em geral por simples oposição aos vegetais terrestres pluricelulares.
