What best describes a Synura colony?

A Synura colony is a type of unicellular green algae that forms spherical or ovoid clusters, typically composed of numerous flagellated cells. These colonies are characterized by their golden-brown color due to the presence of chlorophyll and accessory pigments. They are commonly found in freshwater environments and are notable for their ability to move through water using their flagella. Synura colonies play a significant role in aquatic ecosystems as primary producers and contribute to the food web.
