説明

The structure of spermatozoid of Sargassum Horneri has been studied by means of the electron microscope.<br>1. The body of the spermatozoid is too thick for the electron beam penetrance in the light field of the electron microscope. In the image however obtained in the dark field of the electron microscope, a round dense mass conld be seen. This dense mass may be a nuclear portion of the spermatozoid, which is considered also from the data obtained by the cytological nuclear stain reactions.<br>2. The two flagella of spermatozoid have a plasmic sheath, and only the front flagellum has natural distinct hairy structures, mastigonemes.<br>3. The axis of the flagellum consists of many fine fibrils.<br>4. The front and hind flagella are connected with each other at the blepharoplast of the body.
