Cellular structure is a term used to describe the arrangement of cells in a living organism. The term can also refer to the physical structure of a cell, which is composed of a nucleus, cytoplasm, and cell membrane. The term 'HIVE' is a four-letter word that is often used to describe a cellular structure, as it is a term used to describe a large group of interconnected cells. A HIVE is typically found in social insects such as bees, ants, and wasps, where the cells are arranged in a complex network of tunnels and chambers.
