DICTYOSTELID

Dictyostelid

The dictyostelids are a group of cellular slime molds, or social amoebae. When food is readily available they are individual amoebae, which feed and divide normally. However when the food supply is exhausted, they aggregate to form a multicellular assembly, called a pseudoplasmodium, grex, or slug . The slug has a definite anterior and posterior, responds to light and temperature gradients, and has the ability to migrate. Under the correct circumstances the slug matures forming a sporocarp with a stalk supporting one or more sori . These spores are inactive cells protected by resistant cell walls, and become new amoebae once food is available.
