What is the cytoplasm of a plasmodial slime mold called?

Slime molds can generally be divided into two main groups. A plasmodial slime mold is enclosed within a single membrane without walls and is one large cell. This “supercell” (a syncytium) is essentially a bag of cytoplasm containing thousands of individual nuclei.

Are slime molds harmful to humans?

Slime molds are not known to be a danger to human or animals. Chemical treatment is not warranted for this problem. These organisms are very sensitive to the environment. Slime molds do not survive well in dry conditions.

Do slime molds show social behavior?

Not only do slime molds play an integral part of our ecology, but their social behavior also provides important insight into the inner workings of communication, movement, and altruism.

Are slime molds unicellular or multicellular?

When all is well, the slime mold thrives as a single-celled organism, but when food is scarce, it combines forces with its brethren, and grows. Starving amoebas work in tandem, signaling to each other to join and form a multicellular mass, like a “moving sausage,” Spiegel said.

Why are slime molds useful for cytoplasmic streaming?

These “giant cells” have been extremely useful in studies of cytoplasmic streaming (the movement of cell contents) because it is possible to see this happening even under relatively low magnification. In addition, the large size of the slime mold “cell” makes them easier to manipulate than most cells.

What kind of organism is a slime mold?

The organisms exist as a mass of cytoplasm with diploid nuclei. This mass is a plasmodium. Cytoplasmic streaming can be seen within the plasmodium. Slime molds are excellent research tools because they are large and easy to cultivate.

How big does a plasmodial slime mold get?

Slime molds are a group notable for its unwillingness to be neatly classified! Frequently bright in color and large in size (up to 30 cm in diameter), plasmodial slime molds consist of many amoeba-like cells, which form a mass of protoplasm called myxomycota. The organisms are capable of very slow, creeping movement by

Why are slime molds a good research tool?

This mass is a plasmodium. Cytoplasmic streaming can be seen within the plasmodium. Slime molds are excellent research tools because they are large and easy to cultivate. As long as a food supply is adequate and other environmental conditions are optimal, a slime mold grows indefinitely in its plasmodial stage.
