Kingdom Protista Protists are a category of organisms that are very diverse. They are defined as any organisms that are not a plant, animal, fungus or prokaryote. They are often referred to as the garbage category of classification as their categories of species have only some characteristics of plants, animals, fungus and prokaryotes.

They range from single celled organisms to large masses of organisms. They are by far, the most diverse kingdom of all organisms. They are usually broken into three main categories: animal-like protists, plant-like protists and fungus like-protists. The majority of protists are benevolent organisms, but some can be parasitic. It is believed that protist are about 1.5 billion years old.

Some evolutionary scientists would place them as some of the first eukaryotic life on Earth. Animal-like protists can be broken into four sub-categories: Zooflagellates, Sarcodines, Ciliates and Sporozoans. Giardia Zooflagelates are so named because most of them possess one or two flagella. The flagella help to propel them through their environment using a whip-like tail. They are most commonly found in lakes and streams.

Some Zooflagelates are parasitic, but most are not. Some examples are: Giradia lambia and Trichomas vaginalis.

Amoeba Sarcodines are also animal-like protists that use pseudopods for movement and feeding. A pseudopod is an extracellular projection that flows with a fluid membrane for movement called cytoplasmic streaming. Pseudopods can be used for feeding when they engulf their food and internalize it for digestions.

The best known and most studied Sarcodine is the amoeba. The amoeba also has an additional organelle known as a contractile vacuole. The contractile vacuole is used by the amoeba to remove excess water.

This prevents the amoeba from bursting in fresh water environments. Paramecium Ciliates are animal-like protists that can be found in fresh water and in salt water. They are named for the cilia that line the outer portion of their bodies. The cilia beat quickly to help them move very quickly. Most Ciliates contain a contractile vacuole to help maintain homeostasis. A common example of a Ciliate is the Paramecium. The Paramecium has a very unusual way of creating genetic variety.

It has both a micronucleus and a macronucleus filled with genetic information. The micronucleus is a back-up copy of important genes for the organism. When two Paramecium go through conjugation, they get very close to each other and exchange micronuclei. The new micronucleus migrates to the macronucleus where the new genes are integrated into the genome of the organism.

Sporozoans are the last category of animal- like protists. They are usually parasitic, or disease causing. The best known Sporozoans cause Malaria and African Sleeping Sickness. Malaria is caused when the Sporozoan named Plasmodium is carried by a female Anopheles mosquito to a human.

When the mosquito bites the human, tiny sporozoites can enter the blood stream. They will then incubate in the liver and move on to attack red blood cells.

It is believed that humans who carry the gene for Sickle Cell Anemia are immune to this protist. Sickle Cell Anemia may have evolved as a human combat tool to evade infection from this parasite protist.

Plant-like Protists are broken into the following categories: Unicellular and Multicellular. The unicellular plant-like protists include: Eugleophytes, Dinoflagellates, Chrysophytes, Diatoms, and Unicellular Algae.

Euglena Eugleonphytes, also known as Euglea are an interesting type of protist that is both autotrophic and heterotrophic. Euglena uses an eyespot to sense light. When light is abundant, it will make its food as an autotroph with photosynthesis. When light is scarce it has the ability to switch to a heterotroph. Diatoms are beautiful Dinoflagellates that have calcium carbonate in their bodies. They make intricate and beautiful arrays of designs. Some dinoflagellates are harmful.

They have the ability to bloom when there are too many nutrients in ocean environments. They are commonly known as red tides. Some Dinoflagellates are unique because they can bioluminesce. Bioluminescent diatoms will glow a bluish color in the ocean when agitated. Chrysophytes are very important to marine life. The most common Chrysophyte is phytoplankton. Phytoplankton is often referred to as the base of all marine food chains.

It is the plant-like version of grass in the ocean. Many first order heterotrophs depend on phytoplankton for survival.

Chlamydomonas Unicellular Algae like Chalymdomonas are great examples of a single celled organism. The possess contractile vacuoles, but also have chloroplasts. Fungus-like protists include the following: Cellular and Acellular Slime Molds. Cellular Slime molds are masses of fungus like protists that have both sexual and asexual life cycles.

Most cellular slime molds will only reproduce sexually when they are under optimal conditions. They love moist environments where their amoebas can creep to obtain nutrients. When conditions become unfavorable, they mass into a large aggregate that will migrate to a new location.

They are highly mobile and can move a fair distance. Acellular slime molds only reproduce sexually. They have the ability to aggregate as well.

They will form a fruiting body when conditions are not favorable. The fruiting body will release spores with a very hard outer covering. These spores can resist very long periods of dryness and dessication. When conditions are good, the spores will create a new slime mold.
