What is the tiny cell that allows slime molds to reproduce called?
For the Myxomycetes, the are called myxoamoeba or swarmers (if they have flagella). For the Dictyosteliomycetes, they are amoeba.
Cellular slime molds can be distinguished from plasmodial slime molds on the basis of what?
Cellular slime molds are distinguished from plasmodial slime molds by the presence of individual, distinct cells that remain separate even during the feeding stage. In contrast, plasmodial slime molds have a multinucleate, single cell mass during feeding.
Why are slime molds considered unusual?
Slime molds are considered unusual because they exhibit characteristics of both animals and fungi. They can move, engulf their food like an animal, and also reproduce like fungi. Slime molds also have complex life cycles and unique mechanisms for navigating their surroundings.
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
1. Is the cell the fundamental unit of life In plasmodial slime molds?
Yes, the cell is considered the fundamental unit of life in plasmodial slime molds, which are a type of protist. However, these organisms exhibit a unique characteristic where they exist as a multicellular structure called a plasmodium, formed by the fusion of many individual cells that can share cytoplasm and nutrients. This allows them to function as a single entity while still being composed of numerous cells. Thus, while cells are the basic building blocks, plasmodial slime molds demonstrate a complex level of organization beyond individual cells.

Is slime mold a vertebrate?
No, slime molds are unusually large single cell organisms.

How are cellular slime molds different from acellular slime molds?
A cellular organism produces ATP (either infecting another organism or not), has ribosomes being able to originate daughter cells, therefore having species. An acellular organism doesn't match this criteria. Examples are virus and prions.
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.
Why are slime molds considered unusual?
Slime molds are considered unusual because they exhibit characteristics of both animals and fungi. They can move, engulf their food like an animal, and also reproduce like fungi. Slime molds also have complex life cycles and unique mechanisms for navigating their surroundings.

Why slime water molds are not included in kingdom fungi when they resemble with fungi?
Slime molds and water molds (the oomycetes) are not in the fungal kingdom because they are separate evolutionary lineages. This is revealed by phylogenetic analyses using both molecular, morphological, and biochemical data. The kingdom Fungi is united by the presence of chitin in their cell walls, a whiplash flagellum that is oriented on the posterior of the motile cell, the synthesis of lysine using the AAA pathway, plate-like cisternae in the mitochondria, the presence of a Spitzenkorper, and the use of glycogen as a energy storage compound. Slime molds have a anterior whiplash flagella, and oomycetes (the water molds) have a tinsel and whiplash flagella that are laterally oriented. Both of them use the DAP pathway to synthesize lysine and have tubular cisternae in the mitochondria. Slime molds do not have cell walls (I think), and oomycete cell walls are made of cellulose. Oomycetes use mycolaminarin as an engery sotrage compound.
What is the importance of slime molds?
A Slime Mould or Myxomycete is a fungi like organism that has the characteristics of both plants and animals. They are found in the tropics and the temperate zones. They may be beneficial to the further development of pharmaceutical drugs.
