Abstract
1. A basal body is always found at the base of flagellum in the flagellated plants and planocytes studied.
2. In most of the flagellated cells the conjectioplast is seen connecting the basal bodies with nucleus. Accordingly the movement attained by means of the flagellum (or flagella) is thought to be accomplished by cooperative action of the flagellum, basal body, conjectioplast, or rhizoplast and nucleus.
3. The structure of the motor-apparatus is specific to the flagellated cell of every species studied.
