| Abstract: | We present ultrastructural observations on the processes underlying interaction between the spermatozoon and the egg envelopes in Ciona intestinalis. The morphological and cytochemical basis of sperm binding to the chorion and the subsequent steps such as the acrosome reaction and penetration of the spermatozoon through the chorion are described. Some speculations are also presented on the role of the follicle cells in fertilization. |
