What are some non examples of prokaryotic cells?

Prokaryotes are all single-celled organisms, Most of which are as you know bacteria. For example, Escherichia coli bacterium is a prokaryote, as well as the streptococcus bacterium (what causes strep throat). 

Hope this helps! (If not I'm sorry)

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
