What does alga mean?
noun
A simple multicellular or unicellular non-flowering plant that grows in water, typically attached to rocks or other submerged surfaces by a disc-like structure called a holdfast. Algae are photosynthetic, meaning they produce their own food using sunlight, water, and carbon dioxide.
Example
"The lake's surface was covered in a thick layer of green alga, making it difficult to see the water below."
