Question
Chapter 27, Problem 2SYK
Summary Introduction
To describe: The four positive ways in which the prokaryotes have an impact on an individual lives and on the world around them.
Introduction: Prokaryotes are single-celled organisms that belong to the domains Bacteria and Archaea. Prokaryotic cells are smaller than eukaryotes. They have no nucleus and lack organelles. The prokaryotes play important roles for the survival of many organisms.
