How does the fire coral go through respiration? |
Cnidarians such as corals have no circulatory organs or respiratory system. Therefore, the only way they can get CO2 out and O2 in is the same way that all unicellular life does it: diffusion. Oxygen diffuses into the coral's cells and CO2 diffuses out. Corals can get away with this technique (where as higher organisms need a circulatory system) because they have only two cell layers, ectoderm (outside) and endoderm (inside the ecotderm and the gastrovascular cavity), a very thin layer of non-living matrix called the mesoglea in between, and a very close ratio of body volume to surface area exposed to seawater.
