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.

1 Buspirone (BuSpar), an anti-anxiety drug, is used in the treatment of general anxiety disorder.  The benzodiazepines are used to treat general anxiety disorder, social anxiety disorder, and panic disorder.
Other anti-anxiety drugs include the benzodiazepines, such as Valium, Ativan and Xanax. These drugs do carry a risk of addiction or tolerance (meaning that higher and higher doses become necessary to achieve the same effect), so they are not as desirable for long-term use.ome anticonvulsant drugs (such as Lyrica or Neurontin) and some atypical antipsychotics (such as Abilify or Seroquel) are also occasionally used off label to treat anxiety symptoms or disorders.
