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.
What are Protists that move with cytoplasmic extensions are called?
plasmodial slime molds.
Which is NOT true of the slime molds?
Slime molds are not true molds as they belong to a separate group of organisms called the Myxomycetes. They are not plants or fungi, but actually belong to the kingdom Protista. Some species of slime molds can move and exhibit a form of simple intelligence in their foraging behavior.
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.
Protists that decompose dead organisms like insects are called?
Saprozoic protists. They obtain nutrients by breaking down organic matter from dead organisms through the process of decomposition.

The fruiting bodies in cellular slime molds and sporangia in a cellular slime molds?
The fruiting bodies in cellular slime molds serve as structures for spore formation and dispersal, allowing the organism to reproduce. Sporangia in cellular slime molds are specialized structures that contain spores, which are dispersed to new environments to colonize and continue the life cycle. Both structures are essential for the reproductive success of cellular slime molds.

Protists that produce a multinucleate glob of cytoplasm is?
The protist that produces a multinucleate glob of cytoplasm is known as a plasmodial slime mold. These organisms exist as a large single cell with multiple nuclei distributed throughout the cytoplasm. They typically inhabit moist environments and feed on bacteria and decaying organic matter.
Which group of protists acts as a decomposer?
Molds. Molds such as Plasmodial Slime that may grow on wood after a period of rainy weather. Molds are a type of protists. This is a link to what it looks like. http://img1.photographersdirect.com/img/21394/wm/pd1527513.jpg

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
How do plasmodial slime molds manage to circumvent surface to volume?
Plasmodial slime molds, such as Physarum polycephalum, circumvent surface-to-volume constraints by existing as a large, multinucleate cell called a plasmodium. This structure allows for efficient nutrient absorption and distribution throughout its extensive, interconnected network, maximizing surface area relative to volume. Additionally, their ability to dynamically change shape and extend pseudopodia enables them to explore and exploit their environment effectively, further enhancing their surface area for nutrient uptake.
Which are the protist that act like fungi?
Protists that act like fungi are primarily classified as slime molds and water molds. Slime molds, such as those in the group Myxomycetes, share characteristics with fungi during their vegetative phase, forming plasmodial structures. Water molds, belonging to the Oomycetes group, resemble fungi in their filamentous structure and reproductive processes but are more closely related to algae. Both types exhibit heterotrophic feeding habits, similar to fungi.
What are protist that don't resemble plants animals or fungi called?
Slime molds do not resemble plants, animals, or fungi.
