Foraminifera (forams)
Forams are all marine
Named for their porous shells
Hardened with calcium carbonate
Chalk
Mycetozoa (Slime Molds)
Mycetozoa “fungus animals”
They decompose leaf litter like fungi
But they are not fungi
Use pseudopodia for movement
Two distinct groups
Plasmodial slime mold
Cellular slime mold
Myxogastridia (Plasmodial Slime Mold)
Most are brightly colored
All are heterotrophic
Life cycle contains:
Feeding stage (mobile)
Large mass of unicellular organisms that is not separate by cell walls
Fruiting body (not mobile)
Dictyostelida: Cellular Slime Mold
Feeding stage consists of individual cells
When food is scarce form an aggregate that functions as a unit
