Question

Question 4 Modern slime molds lend support to an explanation for the origins of multicellularity. This explanation relies on the assumption that: the fruiting bodies (stalks) derived from the slug-like state release reproductive spores the slug-like multicellular form must have been the product of multiple species combining individual cells began responding to environmental signals by avoiding each other aggregating cells of some ancient species retained the multicellular state permanently

Answer 1

Slime mould multicellularity is conditonal, not obligate. When food is scarce, individual cells tend to aggregate.

Fruiting bodies(stalk) derived from slug like state release reproductive spores . This shows that slime mould multicellularity is marked by specialisation and differentiation of cell types.
