The word "alga" refers to a group of aquatic, photosynthetic organisms. The spelling of this word is influenced by its pronunciation. According to IPA phonetic transcription, the word is pronounced as /ˈælɡə/. The use of "a" in the third letter of the word is to produce a short vowel sound, while the "g" is used to produce a voiceless velar stop or consonant sound. The proper spelling of "alga" is important in scientific studies, as well as in written communication.
Alga, also known as algae, is a plural noun referring to a large and diverse group of photosynthetic organisms belonging to the kingdom Protista. Algae are typically found in aquatic environments, including both freshwater and marine habitats, but they can also thrive in a variety of other habitats such as moist soil and rocks. They range in size from microscopic, unicellular species to multi-cellular macroalgae, such as seaweeds.
Algae play a crucial role in the ecosystem as primary producers, using sunlight and chlorophyll to convert carbon dioxide and water into organic compounds through the process of photosynthesis. This process releases oxygen into the environment as a byproduct, contributing significantly to the Earth's oxygen levels. Algae serve as a fundamental food source for various aquatic organisms, and they are also utilized by humans for various purposes. For example, some types of algae are used in food production, as nutritional supplements, in biofuel production, and even in the pharmaceutical industry.
The classification of algae is complex due to their diversity, but they can generally be grouped into three main categories: cyanobacteria (also known as blue-green algae), microalgae (including diatoms and dinoflagellates), and macroalgae (including green, red, and brown seaweeds). Despite the ecological importance of algae, certain species of harmful algae, referred to as harmful algal blooms (HABs), can negatively impact aquatic ecosystems by producing toxins that can harm marine life and even pose risks to human health.

The word "alga" has its etymology rooted in Latin. It comes from the Latin word "alga" which means "seaweed" or "seaweed-like plant". Latin itself borrowed this term from the Proto-Indo-European root word "h₂elǵʰ-", which means "green" or "grey" and is associated with vegetation. The word "alga" has been used to describe various types of aquatic plants, particularly those with simple photosynthetic organisms or multicellular species belonging to the division Chlorophyta, commonly known as green algae.
