Question

Quizplus · Accepted Answer

In cellular slime molds, adverse conditions trigger an aggregation of individual myxamoebas to form a multicellular structure called a slug or pseudoplasmodium. This structure moves as a unit to find a suitable location for the formation of a fruiting body, from which spores are eventually dispersed. The formation of sporangia and release of swarm cells from fruiting bodies occur at later stages of the life cycle, after the slug or pseudoplasmodium has formed. Cytoplasmic streaming is a common feature of many eukaryotic cells and is not specifically triggered by adverse conditions in cellular slime molds.
