Summary
The organization of the female genital apparatus of the bdelloid rotifer Philodina roseola was analyzed by light and electron microscopy. It differs from that of the monogononts in several respects: the gonad is paired; in each gonad, the follicular layer completely surrounds the syncytial vitellarium and the cluster of ovocytes; the cytoplasmic bridges between the vitellarium and the immature ovocytes exist but are much narrower; a specialized junction (5–8 nm intercellular space) is established between the follicular layer and the whole area of the germo-vitellarium complex. Preliminary observations about the movements of organelles during ovogenesis were made at an ultrastructural level.
