Photosynthetic lamellae of Prochloron (Prochlorophyta) associated with the Ascidian Diplosoma virens (Hartmeyer) in the vicinity of Townsville

Abstract

Prochloron, the microscopic algae contained within the cloacal cavity of the ascidian Diplosoma virens; possesses fine structures similar to that of blue-green algae. However, the photosynthetic lamellae are composed of two appressed thylakoids, a feature slightly removed from the non-appressed thylakoids of prokaryotic blue-green algae.
