Dictyostelium Discoideum Is an Unusual Organism,one That Straddles the Boundary

Dictyostelium discoideum is an unusual organism,one that straddles the boundary between the unicellular and the multicellular.Its feeding phase consists of individual amoeba-like cells that move independently,feeding on bacteria by phagocytosis.When the food runs out,cells begin to aggregate into a multicelled structure that migrates toward light.The cells differentiate into a base,stalk,and spores; only the spores survive to colonize a new habitat.What is the advantage of forming spores?

A) Spores can mate with other species.
B) Spores are smaller and can be transported to new habitats.
C) The spores are photosynthetic.
D) The spores will eat the other cells.
E) Spores have flagella and can swim to new habitats.
