Farn. Ausbildung eines lateral stehenden Meristems an Prothallien, Differenzierung zu Antheridien. Antheridienbildung an wenigzelligen Chloronemafäden durch Applikation von Gibberelline. Hinausschleudern der Spermatozoide durch Turgormechanismen, Abstoßen der Wand, Strecken des Kerns. Eindringen der Spermatozoide in den Archegoniumhals. Mit Zeitraffung.

Fern. Formation of lateral meristem on the prothalli; differentiation to antheridia. Formation of the antheridia on chloronema threads - each of which consists of only a few cells - through application of gibberellin. Slinging of the spermatozoids by means of a turgor mechanism; sloughing of the wall; stretching of the nucleus. Penetration of the spermatozoids into the neck of the archegonium.
