Amoeboid (Chaos carolinensis)
[image] |
|
Definition
Chaos are animal like protists.
It can crawl and swim.
They eat bacteria, algae and other protists by encircling it and then are broken down by enzymes.
They have as many as a thousand nucleus. |

Term
Ciliate (Hypotrich)
[image] |
|
Definition
Ciliate Hypotrich are animal like.
They eats bacteria and algea.
They moves by crawling or swiming.
The only ciliate that can cause deases is balantidium coil
used for food gathering. |

Term
Flagellates (Giardia lamblia)
[image] |
|
Definition
They are animal like protists.
Like bacteria, they don't ingest whole food. They take in food that is already partially "digested."
Their movements are described as tumbling leaf motility, using their 4 pairs of flagella for locomotion
Giardia lamblia causes human disease. Giardiasis is an infection of the upper small bowel, which may cause diarrhoea. |

Term
Sporosoans (Plasmodium)
[image] |
|
Definition
They are animal like protist.
They enter liver parenchyma cells of their host, where they divide and form merozoites
All sporozoans are parasites that feed on the cells and body fluids of their host animals.
They are used in research.
Plasmodium is the most famous type of sporozoan since it causes the disease malaria. |

Term
Diatoms (Fragillaria)
[image] |
|
Definition
They are plant like protist.
They reproduce by cell division. The diatom becomes smaller with each round of replication.
Diatoms fragillaria produce food by photosynthesis.
They are great suppliers of oxygen. They are producers within the food chain. They are useful in studies of water quality.
No information about possible disease caused by Fragillaria. |

Term
Euglenoids (Euglenales)
[image] |
|
Definition
They are plant like protist.
Their strips can slide past one another, causing an inching motion called metaboly. Otherwise they move using the flagella.
As with other Euglenozoa, the primitive mode of nutrition is phagocytosis. Prey such as bacteria and smaller flagellates are ingested through a cytostome, supported by microtubules.
Some members of the group are parasitic, and can cause severe illness in their human hosts. |

Term
Dinoflagellates (Noctilucales)
[image] |
|
Definition
They are plant like protist.
It can be bioluminescent when disturbed.
It feeds on other plankton, and there is usually a special tentacle involved in ingestion. It engulfs its food (phagotrophic) which primarily consists of plankton, including diatoms and other dinoflagellates, as well as fish eggs and bacteria.
It does not appear to be toxic, but as they feed voraciously on phytoplankton high levels of ammonia accumulate in these organisms may add to the neurotoxic chemicals being produced by other dinoflagellates, such as Alexandrium spp. or Gonyaulax spp., that do result in the death of other aquatic life in the area. |

Term
Red Algae (Palmaria palmata)
[image] |
|
Definition
They are plant like protist.
Palmaria palmata is to be found growing from mid-tide of the intertidal zone (the area between the high tide and low tide).
For their food, since they are photosynthetic, they use energy from sunlight. They use floridean starch as food reserve.
They are a traditional part of European and Asian cuisine and are used to make other products like agar, carrageenans and other food additives.
Galls, possibly produced by nematodes, copepods and bacteria are known to infect these plants. |

Term
Brown Algae (Macrocystis pyrifera)
[image] |
|
Definition
They are plant like protist.
It is one of the fastest-growing organisms on Earth. They can grow at a rate of two feet a day to reach over 45 metres (148 ft) long in one growing season.
For their food, since they are photosynthetic, they use energy from sunlight.
Many marine animals that depend on this algae for food or shelter. Humans harvest kelp for its rich iodine, potassium, and other minerals, but the primary product obtained from giant kelp is alginate.
No information about the possible disease they can cause. |

Term
Slime Molds (Physarum)
[image] |
|
Definition
They are fungi like protist.
When a slime mold mass is physically separated, the cells find their way back to re-unite.
They absorb nutrients from their environment : from soil, decaying wood, or animal dung.
These "giant cells" have been extremely useful in studies of cytoplasmic streaming (the movement of cell contents) because it is possible to see this happening even under relatively low magnification. In addition, the large size of the slime mold "cell" makes them easier to manipulate than most cells.
Some of them can cause cabbage club root disease and powdery scab tuber disease. |

Term
Green Algae (Mesostigma)
[image] |
|
Definition
They are plant like protist.
They grow as an appressed and branched network.
They are photosynthetic eukaryotes, so it means that they use the energy from sunlight : they contain chlorophyll, which they use to capture light energy.
They have an ecological role : At the base of the food chain; they help to purify sewage. Humans use them in biological research.
No information about their possible cause of disease. |

Term
Water Molds (Chytridiomycota)
[image] |
|
Definition
They are fungi like protist.
Their reproductive cells have a flagellum that allows them to swim
They live as saprobes, obtaining their metabolic energy from decaying plant and animal material, or as parasites, attacking plants, fungi, and algae.
Some of them are used in experimental research (e.g. Allomyces).
The chytrid is responsible for a recently discovered disease of amphibians, chytridiomycosis, which is known to kill amphibians in large numbers. Chytrids may also infect plant species and are an important potato pathogen. |

Term
Downy Mildews (Peronospora farinosa)
[image] |
|
Definition
They are fungi like protist.
They grow mainly on lower surfaces of leaves, but spread to the upper surface in wet conditions.
They use nutrients in soil and in their environment, especially potassium and phosphorus.
They can attack all green tissue with functioning stomata, which include the underside of leaves, shoots and flowers. Downy mildew can be extremely devastating if infections are permitted to establish early especially before flowering.
No information about their possible use. |
