Definition of cellular

The word "cellular" has its roots in the Latin word "cellula", meaning "small room" or "little chamber". This Latin term is derived from the word "cella", which referred to a small, enclosed space. In biology, the term "cellular" was first used in the 17th century to describe the smallest units of living organisms, which were referred to as "cells". This term was coined by Antonie van Leeuwenhoek, a Dutch scientist who was one of the first to observe and describe microorganisms using a microscope. Over time, the term "cellular" has been adapted to describe not only living cells, but also cellular networks, cellular phones, and even cellular structure in art and architecture.
