Ergänzende Untersuchungen zur Ultrastruktur von Trichoplax adhaerens F.E. Schulze (Placozoa)

Abstract

1. Die Zellen des Ventralepithels bilden keine Mikrovilli, sondern ein schwammartiges Maschenwerk gefensterter Leisten und Falten, welches bei der Haftung des Tieres an der Unterlage und/oder bei der extrasomatischen Vorverdauung der Nahrung eine Rolle spielen durfte. 2. Wahrend der Zellteilungen treten typische Centriole an den Spindelpolen auf. 3. Die wachsenden Eizellen phagocytieren Fortsatze der Faserzellen, die als Trophocyten fungieren. 4. Unter den gleichen Bedingungen, die zur Eibildung fuhren, konnen sogen. S-Zellen auftreten. Einige ultrastrukturelle Befunde sprechen dafur, das es sich um Spermien handelt.
