Introduction Protists are not animals, plants, or fungi. They have their very own kingdom called The Kingdom Protista. Protists are a very diverse group. There are over 200,000 of them. They get classified into three main groups, and then get classified further into phyla Protists can be found in everyday surroundings, and they have a big impact on all organisms on Earth.
Research
All protists are eukaryotes and their DNA is found within the membrane-bound nucleus. They can be unicellular or multicellular. Protists have similar cellular structure to other eukaryotes, however, there are differences in their reproductive methods. Some protists reproduce asexually by mitosis while others exchange genetic material during meiosis. Protists are classified into

Protozoans are heterotrophs, usually ingesting bacteria, algae, or other protozoans, which is why they are considered animal-like. Some protozoans are parasites. The animal-like group of protists are ciliates, amoebas, apicomplexans, and zooflagellates.
Plantlike Protists Plantlike protists are called algae. They are plantlike because the make their own food through photosynthesis. Some consume other organisms while others are parasites when light is unavailable for photosynthesis. The groups of plantlike protists include the following: euglenoids, diatoms, dinoflagellates, green algae, red algae, brown algae, yellow-green algae, and golden-brown algae.
Funguslike Protists Funguslike protists are considered funguslike because absorb nutrients from other organisms. Some types of funguslike protists consume other organisms and others are parasites. They are not classified as fungi because they contain small, cylindrical organelles called centrioles. Also, the composition of the cell walls of fungi and funguslike protists are different. The groups of funguslike protists include slime molds, water molds, and downy mildews.

Planarians are free-living, carnivorous flatworms found in the Phylum Platyhelminthes, Class Turbellaria. Although the Phylum Platyhelminthes is known for having the animals with the most parasitic species, the class Turbellaria which consist of the Planaria, are a non-parasitic species. Platyhelminthes which translates to "flat worm" are triploblastic animals. This means that they have three tissue layers, the endoderm, mesoderm, and ectoderm. Planaria also are monoecious organisms, meaning that they have both female and male sex organs in one organism. Another characteristic of the Planaria is that they do not have a true body cavity, meaning that they are acoelomate organisms.
There are many different cells that do many different things. But all of these cells fall into two categories: prokaryotic and eukaryotic cells. Eukaryotic cells contain a nucleus and are larger in size than prokaryotic cells. Prokaryotic cells do not contain a nucleus, are smaller and simpler than eukaryotic cells. Two of their similarities are they both have DNA as their genetic material and are covered by a cell membrane.
Merriam-Webster defines ‘parasite’ as ‘an organism that lives in or on another organism and benefits by deriving nutrients at the host 's expense’.
The vole has long, coarse grayish-brown fur on the upper portion of the body and yellowish fur on the lower portion of the body. It has short ears and a short tail, which is somewhat darker on top.
Parasites can be found within almost all living things. Parasite is defined as a creature that benefits from another entity while harming its host. They can cause a variety of symptoms and are notoriously hard to rid from the body. These creatures can also live within a variety of conditions. Although medical progress has helped the infections and diseases that parasites bring, parasites still are prevalent and prove to be a deadly force of nature.

The name of my species is Hydrilla. The scientific name of this species is Esthwaite Waterweed. The classification is Alismatales because all plants that fall there is either aquatic or tropical. Hydrilla has really impacted our world. The Hydrilla plant may be "good" to goldfish, for the reason that they play with it, yet it can ruin anybody's life. It was brought from another country, but it really impacted people's lives and the ecosystems. Although Hydrilla was originally from warmer parts of Asia, it has spread in some parts of North America. The Hydrilla was found in Florida in 1960 due to the aquarium trade. It impacted our lives and other organisms lives because of the scarce vegetation. In the ecosystem, the hydrilla would kill many
These tiny animals dwelling in the moist areas of our planet looks like a funny little thing. But as we laugh at its weird and peculiar body structure and shape, it is cheating death. These funny tiny animals are called tardigrades, water bears or moss piglets. At first glance these creatures may not make a big impression considering their small stature and unimpressive frame. Soon we learn that although these creatures are funny to look at they can survive in any place in the world you can think of because of cryptobiosis. It is mainly dependent on moisture to survive. They can reproduce asexually and often time consume their habitat making them pretty self-reliable.
The stages in a typical jelly life history are adult, gametes, planula, scyphistoma , strobila , and ephyra. Moon Jellies reproduce sexually and asexually. The adult Moon Jelly reproduces sexually by releasing eggs, and then the sperm over the eggs. Jellyfish can be either male or female so one jellyfish can reproduce entirely on its own (gametes). Once fertilized the eggs develop into small, ciliated planula larvae. The larvae look for a safe protected place to nest and to continue to grow safely. They will stay there until they enter the polyp stage (scyphistoma). Once the scyphistoma has reached a certain growth stage they will begin to elongate and look like they are growing away from its base. This is when they will enter the strobili
In the kingdom of Fungi, is a collection of different organic multicellulary eukaryotic organisms. Fuguses are unique from any other life form. They grow in the wild yet they are not plants. They also breakdown and digest animals and plants alike, but they are not animals. Fungi are made up of chitin, a derivative of glucose that is also found in cephalopods, arthopods and crustaceans alike. Similiar to cellulose which is a what plants' cell walls are comprised of, Chitin is a tough material that gives the Fungi its structure.
The platypus is a fascinating creature that has defied science for many years. They have stumped even scientists just by existing. The platypus is recently known for appearing as one the main characters in the popular kids cartoon “Phineas and Ferb” by Disney Channel. However, the curious creature is not typically a super agent like the cartoon shows us. As cool as that would be, it’s not true. Though the platypus facts are just as awesome as the platypus fantasy. This unique creature has a very interesting history linked to its science and how it behaves in nature. Platypuses are not your typical, everyday find. It is very unique and not just in one or two ways.
Arthropods are animals belonging to the phylum Arthropoda, which is the largest of all phyla in the Animal Kingdom, with more than one million species, making them almost 80% of the whole kingdom. These include insects, arachnids, crustaceans and many more, most of which are quite small, the biggest being the Japanese Spider Crab with a leg span of 3.5 meters and the smallest being the microscopic Plankton.
I found it interesting that the most recognized organisms in the Porifera Phylum are called sponges. In fact, Porifera is the oldest phylum in the kingdom of Animalia, and have been around for the last six hundred million years. Some important characteristics that can be identified with Porifera are: they have no definite symmetry, no organs, no nervous system, mostly have a skeleton of spicules, all filter feeders, multicellular organisms, and they live in aquatic environments. Sponges are a unique and simplistic animal, and have been around for a long time. These sponges can be found in rivers and streams or in the depths of the ocean. Sponges can show a great variety of forms, but their basic organization is quite simple. Sponges are a water filtering system. They have a convenient canal system that helps them receive food and pump water through a canal, which water comes in through pores called ostia. After, it flows through a chamber called spongocoel. It exits through the oscula, which are large openings. Sponges consist of three layers: an outer layer of pinacocytes, an inner and non-living layer with amoebocytes that assist reproduction and bring food particles from the choanocytes to other ...
Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm. In eukaryotic cells the chromosomes remain together inside the nucleus and there is a clear nuclear membrane that is surrounding the nucleus.
Their flesh gradually becomes clear and their white skeleton becomes visible. Moreover, their whole body would be covered by fuzzy microalgae.
