Stromatolites (pictured here) are rocky structures that generally form in shallow waters from the binding of sediment by bacterial microbial biofilms. Stromatolites are typically hypothesized to be formed from the presence of cells that bind these grains together. If the cells that formed the stromatolites were fossilized with these rocks, an analysis of these cells would likely include which structures? A) DNA, nucleus, and ribosomes
B) Mitochondria, DNA, and ribosomes
C) Plasma membrane, nucleus, and DNA
D) Plasma membrane, DNA, and ribosomes
