The fungi-like protists of Kingdom Protista comprise a group including slime molds and water molds. These molds are simple, unicellular organisms that are fungi-like in appearance and habitat, according to Cliffs Notes. By ingesting more complex organic matter, they act as decomposers. Like true fungi, they thrive in moist or wet environments.Continue Reading
Often displaying a slimy appearance for which they are named, there are two primary types of slime molds: cellular and acellular, explains CK12.org. During the feeding stage, both mold types form a mass that propels itself along, ingesting as it goes. Phylum dictyosteliomycota, a cellular protist, retains its cell walls as individual amoebas group together into a slug of protoplasm, while phylum myxomycota, an acellular protist, loses its cell wall, with the amoebas forming a mass with multiple nuclei inside of one cell membrane, called a plasmodium. Both types of molds prefer the damp environment of a rotting log or the forest floor.
Water molds are a separate group of primarily aquatic molds that act as parasites on land. For example, the water mold Phytophthora infestans caused a late potato blight and nearly wiped out the potato crop in mid-19th century Ireland, causing the Irish potato famine. Another water mold, genus Plasmodium, causes malaria in humans.Learn more about Biology
Various protist species are important to humans because they are the primary producers at the base of the food pyramid, turning the energy from the sun into a form that can be passed from organism to organism up the food pyramid. Protists also stabilize the ion levels of water, which allows seaweed and fish, both of which are important food sources for humans, to thrive.Full Answer >
Protists are a diverse group of organisms, and they reproduce in a number of different ways, including asexual binary fission, multiple fission, fragmentation and several forms of sexual reproduction. Many protists can reproduce either sexually or asexually depending on environmental conditions.Full Answer >
The types of protists, which are eukaryotes, that aren't animals, fungi or plants include euglenoza, alevolates, stramenopiles, red algae, slime molds and choanoflagellates. The alevolate group includes ciliates, sporozoans and dinoflagellates. The stramenopile group includes diatoms, golden algae, green algae and water molds.Full Answer >
According to Spark Notes, eubacteria comprise an ancient group and can be saprophytes, photoautotrophs or symbionts. Eubacteria are also known as the true bacteria. They are able to reproduce by binary fission, with a split approximately every 20 minutes.Full Answer >
