The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. In the Charales, the closest relatives of higher plants, full cellular differentiation of tissues occurs.There are about 8,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds.n the Charales, the closest relatives of higher plants, full cellular differentiation of tissues occurs.

Anxiety medications include multiple types of drugs that are used to treat the symptoms of anxiety disorders. The three most commonly prescribed types of anxiety medication are antidepressants, anti-anxiety medications (also known as anxiolytics), and beta-blockers. Antidepressants and anxiolytic medications work primarily by affecting the balance of certain chemicals in the brain known as neurotransmitters. Beta-blockers and other types of drugs are used to address the physical symptoms that may accompany an anxiety attack.
