Abstract
We focused attention of the calcification ability of coral cells. A section of coral was transplanted to the cavity of a tooth and observed microscopically for calcification after 7 days (LI group) and 14 days (LII group) of artificial irradiation. Observation after 7 days (NI group) and 14 days (NII group) without artificial irradiation was used as a control. Calcification was observed in the LI and LII groups, while it was not observed in the NI or NII group. The results suggest that coral contains single-cell xanthella which accelerate calcification by photosynthesis.
