| 11. | Radula with tricuspid central tooth with square basal plate, as large as the bicuspid laterals, the marginals multicuspid.
|
| 12. | In the first marginal tooth, the main cusp is less symmetrical and the basal plate is less prominently developed.
|
| 13. | The tendrils will later form the basal plate of the adult sponge that firmly anchors the animal to the reef.
|
| 14. | The ventral part of the neural tube is called the basal plate; the dorsal part is called the alar plate.
|
| 15. | The optical vesicle ( which eventually become the optic nerve, retina and iris ) forms at the basal plate of the prosencephalon.
|
| 16. | The root cluster attached to the basal plate of the bulb is the only part not typically considered palatable in any form.
|
| 17. | The basal plate is used to scrape smaller organisms off of the grains of sand that make up their anoxic seabed mud habitat.
|
| 18. | This dorsal spine is fitted over a long basal plate and articulating at its base with the apex of a high triangular fin.
|
| 19. | True twin-scaling involves further subdivision of the chips to create pairs of scales, joined together by a small part of the basal plate.
|
| 20. | The alar plate of the prosencephalon expands to form the cerebral hemispheres ( the telencephalon ) whilst its basal plate becomes the diencephalon.
