What is the function of gastrodermis?
The gastrodermis is a tissue layer found in organisms such as cnidarians (e.g., jellyfish and corals) that lines the digestive cavity. Its primary function is to facilitate digestion and nutrient absorption, as it contains specialized cells that secrete enzymes to break down food particles. Additionally, the gastrodermis plays a role in the overall physiology of the organism, contributing to the distribution of nutrients throughout the body.
What is the function of a nematocyts?
Nematocysts are specialized stinging cells found in cnidarians, such as jellyfish, sea anemones, and corals. Their primary function is to capture prey and provide defense against predators. When triggered, nematocysts release a coiled thread that can inject toxins into the target, immobilizing or harming it. This mechanism is essential for the survival and feeding of these marine organisms.

What symmetry do coral have?
Coral exhibit radial symmetry, which means their body structure is arranged around a central axis. This allows them to have multiple identical sections radiating outward, similar to the spokes of a wheel. This symmetry is particularly evident in the arrangement of their polyps, which are the individual coral animals. Some corals may also show bilateral symmetry in certain stages of their life cycle or in specific species.
What does Cnidaria Scyphozoa mean?
coelenterates in which the polyp stage is absent or at least inconspicuous: jellyfishesCnidaria is a phylum whose organisms are: radial in symmetry, may have cnidocytes (stinging cells), Diploblastic tissues, no coelomic cavity, two basic types of individuals: polyps (sessile - no capable of moving) and medusas (free floating). Three classes are found in Cnidaria: Hydrazoa, Scyphozoa (ex. Jellyfish), and Anthozoa (ex. corals)

Differences between hermatypic and ahermatypic corals?

How many reef building corals are in the Great Barrier Reef?
Not all corals are reef-building. The IUCN (International Union for Conservation of Nature) has determined that there are some 875 reef-building coral species worldwide. 27% of these are threatened, and another 20% are near- threatened, while there is insufficient data on another 17%.In the Great Barrier Reef itself, it is estimated there are about 350 species of reef-building corals.

Does corals eat zooxanthellae?
No corals doesn't eat zooxanthellae they only eat zooplankton. Zooxanthallae helps corals to live and keeps corals colourful.They live on the coral polyps.
How does algae benefit the corals?
Many corals, specifically hermatypic corals, contain symbiotic algae that provide the coral with sugar from photosynthesis. Algae also feed zooplankton, which corals feed on. Basically, algae provide corals with food, indirectly.
