ESTEVEZ, José M.  e  CACERES, Eduardo J.. Fine structural study of the red seaweed Gymnogongrus torulosus (Phyllophoraceae, Rhodophyta). Biocell [online]. 2003, vol.27, n.2, pp.181-187. ISSN 0327-9545.

The present study analyzed several characters of the red seaweed Gymnogongrus torulosus, such as cellular structure of the thallus, cuticle, pit plug and cell wall ultrastructure, and morphology of some organelles like plastids, Golgi bodies and mitochondria. Also, anomalous chloroplasts with thylakoid disorganization were found in medullary cells. The significance of this thylakoid disposition is still unclear. This is one of the first studies focused on the fine structure of a red alga recorded in Argentina.
