  1. Myxogastria By: Rick Maas

  2. Classification Information • Common Name: Plasmodial Slime Molds • Scientific Name: Myxogastria • Kingdom name: Amoebozoa • Phylum name: Mycetozoa • Class Name: Myxogastria

  3. Common Characteristics • Evolutionary: cellular communication and differentiation • Symmetry: mostly bilateral but some are asymmetrical • Pseudeocoelomate • A. Parasistic • B. Decomposers • C. Terrestrial • No segmentation

  4. Life Cycle/ Reproduction • Lifespan: differentiates depending on: • Conditions • Resources • Ability to reproduce • Syncytial Reproduction (Asexual) A cell germinates and cracks releasing another cell. This cell (myxamoeba) will eat and survive till it find another same mating cell. They come together and form a zygote. This zygote will split it’s nucleus in the same cell. During this split, the cell releases plasmodium which is what you see when you see the slime molds. This layer makes spores so the cycle starts all over again. • Syncytium: “a super cell”; one cell with many nuclei.

  6. Description of Habitat/ Niche • Habitat: • Dead Plants • Forests • Soils • Lawns • Niche • Bacteria • Yeasts • Decomposing Matter

  7. Interesting Characteristics • Plasmodium matter that forms around the cell actually can cause diseases. (Also found in Malaria) • Scientists use this cell the most to study asexual reproduction because it is one of the biggest single cell organism. • Scientists also found out that it can go through mazes to find a good place to habitat. They put the cell in control of a robot and the robot was found within a small, dark corner. This is weird because it doesn’t have a nervous system. • Also Mycetozoa were once considered fungi but after some research has been done, more scientists have considered them more protists. • These slime molds can be seen in many different colors. What you see is the plasmodium which includes the colors red, orange, yellow, and others.
