German | German Dinoflagellat. Entwicklung von acht mondsichelförmigen Sekundärzysten aus einer kugelförmigen Primärzyste, Entstehung von meist fünf bis acht zweigeißeligen Zoosporen (Dinosporen) in jeder Sekundärzyste, Freiwerden der Dinosporen, Enzystierung einer Dinospore. |
English | English The peridinian Dissodinium lunula is a cosmopolite of marine coastal plankton. It multiplies vegetatively by multiple fission. At first, from a spherical primary cyst eight lunate secondary cysts develop. Finally, from each of these five to eight biflagellated zoospores usually arise. D. lunula has a large nucleus, whose numerous chromosomes become clearly visible already in vivo. As to the observation of the nuclear division young uninucleated secondary cysts were best appropiate. |
