Final answer:
Cell communication is a fundamental process found in both eukaryotic and prokaryotic organisms, implying a shared evolutionary heritage and a foundational role in the biology of all living cells.
Step-by-step explanation:
Cell communication is found in both eukaryotes and prokaryotes, suggesting a common mechanism in all cells. This indicates that intercellular communication is a fundamental aspect of life that evolved early in the history of living organisms. While eukaryotic cells, such as plant cells, animal cells, and fungal cells, possess complex structures like organelles to facilitate intricate functions, including communication, prokaryotic organisms such as bacterial and archaean cells also engage in sophisticated communication networks. This is exemplified by quorum sensing in bacteria, a process of chemical communication that coordinates behavior among cells.
In conclusion, the correct choice that answers the question is (b) Found in both, suggesting a common mechanism in all cells.
