I would like to ask this question from Two Fundamentally Different Classes of Cells topic in portion Introduction to Cell of Cell Biology

Answer 1

Right answer is (c) Complex, multispecies communities

The explanation: Prokaryotes such as bacteria were initially thought to be solitary creatures, but they are capable of living as complex communities called as biofilms. A biofilm is defined as a group of microorganisms in which cells stick or adhere to a living or non-living surface. These adherent cells become embedded within a slimy extracellular matrix composed of extracellular polymeric substances (EPS).
