There is an amazing generator converts solar energy into storable energy for the coral —- symbiotic algae. It also takes the coral’s nitrogen waste and converts to usable nutrients. What’s even more amazing is that as corals grow, the algae can self-replicate and increase in numbers.
Coral have ectoderm and endoderm. Symbiotic algae almost occupies the entire endoderm, it can carry out photosynthesis, provide nutrients and dye beautiful color in coral. Zooxanthellae solidify CO2 through photosynthesis and stimulate coral to form calcium shells. The coral bleaching is caused by the breakdown of the close symbiosis relationship, and corals that have long lost the algae gradually die.
Q: How do coral control the division of symbiotic algae cell?
A: Algae cell only split when stimulated by blue light. Coral use green fluorescent protein absorb and block blue light to maintain algae not to divide too much in body.
Inspired by coral, I generate models by random points connection and density interference. Do biome grow in models like they live in reefs? Yes. Move forward, How does algae symbiosis with a porous model? As living environment, the experiment goal is to make multi-models that supply illumination, temperature control and PH filter, also provide nitrogen for algae.

my client’s profile
Sarcophyton has multiple tentacles with a mouth in the center. It is a marine coelenterate that feeds on tiny plankton in and out of its mouth in the ocean.
The coral polyps absorb calcium and carbon dioxide from seawater as they grow, then secrete limestone to form their shells. The coralis the secretion of the polyps, which forms the supporting structure like skeleton.
They living in a swarm groups, the polyps have skeletons attached together, and intestinal cavities are attached through the intestinal system too, so the polyps have many mouths but share only one stomach.
