al·ga

 (ăl′gə)
n. pl. al·gae (-jē)
Any of numerous photosynthetic organisms of aquatic or moist habitats, ranging in size from single-celled diatoms to large seaweeds such as kelp, and characterized by a lack of complex organs and tissues. Once classified within the plant kingdom, the algae are now considered to include several unrelated groups belonging to different kingdoms.

[Latin, seaweed.]

al′gal (ăl′gəl) adj.

al·ga

(ăl′gə)
Plural algae (ăl′jē)
Any of various green, red, or brown organisms that grow mostly in water, ranging in size from single cells to large spreading seaweeds. Like plants, algae manufacture their own food through photosynthesis. They form a major component of marine plankton and are often visible as pond scum. Although they were once classified as plants, they do not have roots, stems, or leaves, and are now viewed as protists.
