When slime molds likely gather to form one large structure?
when food and water are scarce :)
Slime molds water molds and downy mildew's are examples of what Protists?
Slime molds and water moldsThe fungus -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.Read more: Protista - Slime Molds And Water Molds http://science.jrank.org/pages/5547/Protista-Slime-molds-water-molds.html#ixzz0d6EfuAiF

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.
Is it true that the haploid stage dominates the cellular slime mold life cycle whereas the diploid stage dominates the acellular slime mold life cycle?
Yes, that is correct. In cellular slime molds, the haploid stage, also known as the amoeboid stage, dominates the life cycle. These amoeboid cells undergo aggregation to form a multicellular structure called a slug. On the other hand, in acellular slime molds, the diploid stage, or the plasmodial stage, dominates the life cycle. The plasmodium is a large, multinucleate mass of cytoplasm that can give rise to fruiting bodies for spore production.
What are 3 types of decomposing molds?
Molds are considered to be microbes and do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota and Ascomycota. There are Fungi known as molds. Slime molds and water molds are not Fungi.There are Fungi known as molds. Slime molds and water molds are not Fungi.
Are slime molds a ciliate?
Both slime molds and ciliates belong to the protists group. Ciliates are single-celled and slime molds have a complex life cycle during the course of which they go through unicellular, multicellular, funguslike (form spores) and protozoanlike (amoeboid) stages.
When the amoebalike cells of acellular slime molds fuse they form structures with many nuclei called?
plasmodia

Acellular slime molds in phylum myxomycota form a slug like mass known as a?
pseudoplasmodium
Are slime molds multicellular or unicellular?
Two broad groups of slime molds are recognized. The individual cells of cellular slime molds remain distinct-- separated by cell membranes-- during every phase of the mold's life cycle. Slime molds that pass through a stage in which their cells fuse to form large cells with many nuclei are called acellular slime molds.

What kinds of fungus can move?
Certain kinds of slime molds, which are commonly regarded as fungi, can move. Slime molds come in different types, one of which is called "cellular." The cellular slime mold starts as an amoeba-like or yeast-like cell that divides into multiple, individual cells. The amoeba-like cells move on their own. Eventually, slime mold cells combine into a single body, and such a body sometimes looks and acts much like a common slug. In this form it moves about in quest of a place to go to the next stage in its life. The next step is for the combined body to differentiate into a stem and a fruiting body, and at this stage it may appear to be very like a mold.
How do water molds get there food?
Mycelium It reaches out like an arm and connects to an adjacent area, it then grows again and branches out as far as the conditions will allow.
