Symbiodinium These unicellular algal protists commonly reside in the endoderm of tropical cnidarians such as corals, sea anemones, and jellyfish, where the products of their photosynthetic processing are exchanged in the host for inorganic molecules.ymbiodinium are colloquially called  zooxanthellae  (or  zoox ), and animals symbiotic with algae in this genus are said to be zooxanthellate.

- The fungus-like protists are the slime molds and water molds. They are mostly single-celled organisms that live in the moist soil of forest floors and compost piles. These heterotrophs absorb nutrients from decaying organic matter and move in the same fashion as amoebas by extending and pulling with pseudopodia.esson Summary. Kingdom Protista contains the protists, or all the organisms that do not fit into the other kingdoms of life. Protists can be heterotrophic or autotrophic, mobile or immobile, single-celled or multi-celled, solo or a member of a colony.

Coral reef Coral reef. Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine water that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support a

Corals get their food from algae living in their tissues or by capturing and digesting prey The algae live within the coral polyps, using sunlight to make sugar for energy. This energy is transferred to the polyp, providing much needed nourishment. In turn, coral polyps provide the algae with carbon dioxide and a protective home. Corals also eat by catching tiny floating animals called zooplankton.At night, coral polyps come out of their skeletons to feed, stretching their long, stinging tentacles to capture critters that are floating by.his energy is transferred to the polyp, providing much needed nourishment.

Class Anthozoa  (sea anemone and coral fossils) Corals are marine organisms of class Anthozoa (Kingdom Animalia, Phylum Cnidaria, Class Anthozoa) that typically live in large colonies of identical individuals. They are important reef builders in tropical seas, and are secretors of calcium carbonate (CaCO3) that forms their hard skeleton.

Protist Many protists are flagellate, for example, and filter feeding can take place where the flagella find prey. Other protists can engulf bacteria and other food particles, by extending their cell membrane around them to form a food vacuole and digest them internally, in a process termed phagocytosis.

- Corals and Coral Reefs. Corals are small animals, living in colonies in marine waters; each element of the colony is called a polyp. Polyps secrete calcium carbonate (CaCO 3), a solid compound, which forms a skeleton normally referred to as a coral reef.

- The Protists-Eukaryotic Organisms Kingdom Protista Single-celled, eukaryotic organisms are called protists. They are grouped together in Kingdom Protista. Those protists that are animal-like are put in Subkingdom Protozoa, and the protists that are plantlike belong to Subkingdom Algae.lgae are unicellular or multicellular organisms (formerly classified as plants) that have chlorophyll but lack true stems, roots, and leaves. Algae include the seaweeds, diatoms, and spirogyra. Prokaryotic Organisms-The Cyanobacteria Cyanobacteria belong to Domain Bacteria. These microscopic organisms lack nuclei.

What Is Coral? A Coral Polyp and Zooxanthellae But tropical reef-building corals have tiny plant-like organisms living in their tissue. The corals couldn’t survive without these microscopic algae–called zooxanthellae (zo-zan-THELL-ee). This cutaway diagram of a coral polyp shows where the photosynthetic algae, or zooxanthellae, live—inside the polyp’s tissue. The coral gives the algae a home. In return, the algae provide the coral with food. Learn more in the Ocean Portal's coral reef section and in this zooxanthellae slideshow.

Life Is Found Thriving at Ocean's Deepest Point Other types of protists include algae and slime molds. There are an estimated 4,000 species of living foraminifera. They inhabit a wide range of marine environments, mostly on the ocean bottom, though some live in the upper 300 feet (100 meters) or so of the ocean. A few species are found in fresh water and on land.

- Example sentences. 1  The plants are tiny single-celled algae, the zooxanthellae or symbiotic dinoflagellates, that live within the tissues of corals in great numbers. It is not known whether rugose corals had symbiotic photosymbiotic zooxanthellae as modern corals do. 2  The zooxanthellae in these corals are dinoflagellates, and it is suspected that there may be a relationship between their diversifications.

Protist Protists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.ome protists are significant parasites of animals (e.g., five species of the parasitic genus Plasmodium cause malaria in humans and many others cause similar diseases in other vertebrates), plants (the oomycete Phytophthora infestans causes late blight in potatoes) or even of other protists.

Zooxanthellae Zooxanthellae are single-celled protozoans (dinoflagellates) that are able to live in symbiosis with certain marine invertebrates.In freshwater habitats, similar endosymbionts are known as zoochlorellae.ooxanthellae are photosynthetic organisms, and as well as chlorophyll a and chlorophyll c, contain the dinoflagellate pigments peridinin and diadinoxanthin. These provide the yellowish and brownish colours typical of many of the host species.

- Habitat for Acan Coral Acan Coral, also known as Acan Brain Coral, prefers to live and grow at either the bottom or middle of the coral reef or rock bed on which it stabilizes. While the Acan Coral occurs in several places throughout the world, it is mostly found in the waters surrounding Australia.abitats for Candy Cane Coral. Candy Cane Coral, also known as Trumpet Coral, Torch Coral, Candy Coral, and Bullseye Coral, is a colonial type of coral that can grow anywhere on a coral reef or rock bed. It can also do well in sandy type areas. This coral mostly appears near Fiji.

- In colonial ascidians, the zooids are usually tiny, sometimes microscopic. The colony can range from a few centimeters in diameter to a meter or more, and up to several centimeters thick. Colonial ascidians may grow as slimy layers and blobs on rocks, jetty pilings and other hard surfaces. Some tropical members of the family Didemnidae contain green symbiotic algae in their tunics and inside the bodies of the zooids. These may also contain symbiotic cyanobacteria.

- Still, corals are not the only dominant species found in the coral reef biome. One group of red algae (Phy.

Kingdom Protista Kingdom Protista. All single celled organisms are placed under the Kingdom Protista. The term Protista was first used by Ernst Haeckel in the year 1886. This kingdom forms a link between other kingdoms of plants, animals and fungi.Protists represent an important step in early evolution. The first protists evolved probably 1.7 billion years ago.eneral characteristics of Kingdom Protista are as follows: 1  They are simple eukaryotic organisms. 2  Most of the organisms are unicellular, some are colonial and some are multicellular like algae. 3  Most of the protists live in water, some in moist soil or even the body of human and plants.

- Also, when algae are consumed by other protists, some of the nutrients the algae contain are lost to the environment during feeding. Bacteria can use these dissolved nutrients to grow and flourish. The bacteria, in turn, serve as a food source for protozoa that consume bacteria.rotozoa are classified within a much larger group of single-celled organisms that includes the algae, other single-celled photosynthetic organisms, and some of the water molds (slime molds). This larger group is called the protists (pronounced like “pro-teests”).
