-like protists resemble the fungi during some part of their life cycle. These organisms exhibit properties of both fungi and protists. The slime molds and the water molds are members of this group. They all obtain energy by decomposing organic materials, and as a result, are important for recycling nutrients. They can be brightly colored and live in cool, moist, dark habitats. The slime molds are classified as either plasmodial or cellular by their modes of reproduction. The plasmodial slime molds belong to the phylum Myxomycota, and the cellular slime molds belong to the phylum Acrasiomycota.
The plasmodial slime molds form a structure called a plasmodium, a mass of cytoplasm that contains many nuclei but has no cell walls or membranes to separate individual cells. The plasmodium is the feeding stage of the slime mold. It moves much like an amoeba, slowly sneaking along decaying organic material. It moves at a rate of 1 in (2.5 cm) per hour, engulfing microorganisms. The reproductive structure of plasmodial slime molds occurs when the plasmodium forms a stalked structure during unfavorable conditions. This structure produces spores that can be released and travel large distances. The spores land and produce a zygote that grows into a new plasmodium.
The cellular slime molds exist as individual cells during the feeding stage. These cells can move like an amoeba as well, engulfing food along the way. The feeding cells reproduce asexually through cell division. When conditions become unfavorable, the cells come together to form a large mass of cells resembling a plasmodium. This mass of cells can move as one organism and looks much like a garden slug. The mass eventually develops into a stalked structure capable of sexual reproduction.
The water molds and downy mildews belong to the phylum Oomycota. They grow on the surface of dead organisms or plants, decomposing the organic material and absorbing nutrients. Most live in water or in moist areas. Water molds grow as a mass of fuzzy white threads on dead material. The difference between these organisms and true fungi is the water molds form flagellated reproductive cells during their life cycles.

What else can I help you with?
Are downy mildews unicellular or multicellular?
Downy mildews are multicellular organisms. They belong to the group of water molds and are classified as oomycetes, which are fungal-like protists. These organisms typically form filamentous structures called hyphae, allowing them to grow and spread in their environments, particularly on plants.
What are funguslike protists that sometimes creep together to form a multicellular mass?
These protists share many characteristivd with Fungi. However, because of their differences from Fungi they are classified as protists. Funguslike protists play a valuable role in the ecosystem. They break down dead plant and animal matter, making the nutrients from these dead orgainsms available for living organisms. While some slime molds and water molds are benefical, many others can be very harmful. Many fuguslike protsts attack and consume living plants.
Phylum Oomycota contains the water molds and downy mildews these organisms feed mainly on?
Phylum Oomycota contains water molds and downy mildews, which are parasitic organisms that mainly feed on plants and decaying organic matter. They can cause diseases in plants by infecting the roots, stems, leaves, and fruits.
What characteristics make a protist more animal-like?
1.)most unicellular 2.)some are multicellular 3.)some are multicellular (algoe) 4.)can be heterotrophic or outorophic 5.)most are in water (though some live in moist soil or even the human body 6.)All are eukaryotic (have nucleus)
Where are water molds found?
Most water molds and downy mildews live in water or moist places. These organisms often grow as tiny threads that look like fuzz. CREDITS TO: NORTH CAROLINA 8TH GRADE PRENTICE HALL SCIENCE EXPLORER
What are examples of fungus-like protists?
Examples of fungus-like protists include slime molds, water molds, and downy mildews. These protists exhibit characteristics resembling both fungi and protists, such as forming spores for reproduction and possessing cell walls.
What are the 3 types of funguslike protists?
Slime molds,water molds,and downy mildews
What kind of protist is the mildew that commonly grows damnp areas?
slime mold
Are downy mildews unicellular or multicellular?
Downy mildews are multicellular organisms. They belong to the group of water molds and are classified as oomycetes, which are fungal-like protists. These organisms typically form filamentous structures called hyphae, allowing them to grow and spread in their environments, particularly on plants.
List the names and characteristics of fungus-like protists?
Fungus-like protists include slime molds, water molds, and downy mildews. They are eukaryotic organisms that can exhibit both fungal-like and protozoan-like characteristics. Slime molds are known for their amoeboid movement and ability to form multicellular structures, while water molds and downy mildews are often plant pathogens that form filamentous structures for nutrient absorption.
How are downy mildews and water molds similar?
they both stink
Downy mildews and water molds are similar to fungi in that they both?
Downy mildews and water molds are similar to fungi in that they both resemble fungi. They can also cause diseases similar to fungi.
Do spores produces by downy mildews weaken the plants they live on?
Yes
How do water molds and downy mildews reproduce?
flagellated reproductive cells
Do spores produce downy mildews weaken the plants they live on?
Yes
