The document discusses various types of algae. It contains 20 multiple choice questions about algal taxonomy, characteristics, and classification. Some key details covered include that phycology is the study of algae, algal blooms describe the rapid growth of microscopic algae, Linnaeus first coined the term algae, and certain divisions of algae like Cyanophyta, Rhodophyta, Phaeophyta and Chlorophyta are known as blue-green, red, brown and green algae respectively.
