| dc.description.abstract | Studies of the effects of sunlight in the undetwater environment on the physical and cellular ' features of Acropora nobilis reflects the overall situation of other coral species in Malaysian coastal area. Biophy:sical parameters of corals and zooxanthellae (Symbiodinium microadriaticum)' cell diameter change with the increasing water depth (less light). Regression and correlation statistical tests show that there are strong and significant relationships between ~ome of the parameters studied. These paramenters are between coral weight (g) relation with cover area (cm2 ) ,zooxanthellae count and cover area (cm2 ) and polip count with cover area (cm2 ). However, the results are not consistent for corals from different places. Ten pigments were successfully separated from the zooxanthellae cells, namely chlorophyll-a, chlorophyll-c, peridinin, J3-carotene, neo-peridinin, pheophytin-a, dinoxanthin and diadinoxanthin including two unknown pigments. The two phase thin layer chromatography (TLC) test, spectrophotometry test, RF value estimation (relative running length) and pigment colour verified that the pigments present were the same for different depths sampling. The RF value of the coral pigments can be used to differentiate coral species. The quantity of pigment was at a maximum at 4 metre depth and continued to increased with depth. Generally, light causes cellular and molecular adaptation of the coral to maximize photosynthesis process of its symbionts cells, the zooxanthellae. Zooxanthellae also adapt by increasing their pigment and cell size to capture maximum light and maximizing their photosynthesis rate. | en_US |
