Symbiotic algae provide nutrients. Analogous to fungi in that they have filamentous structure to increase surface area for decomposition. Amoebalike cells used for feeding in both phyla. Cytoplasmic streaming moves mass of cells and distributes O 2 and nutrients throughout mass. Brightly colored pigments.
Ameobalike cells consume bacteria.
Use cAMP to communicate between cell to form fruiting bodies. Used in studies of cell communication. Sexual reproduction occurs. Meiosis within cyst forms haploid cells that are then released to form other amoebalike cells.
