Biological:
* Multicellular organism: This is the most common interpretation. A multicellular organism is made up of many different cells that work together to form tissues, organs, and organ systems. Examples include plants, animals, and fungi.
* Tissue: A group of similar cells that work together to perform a specific function. Examples include muscle tissue, nervous tissue, and epithelial tissue.
* Organ: A structure made up of different tissues that work together to perform a specific function. Examples include the heart, lungs, and brain.
Other:
* Cell colony: A group of individual cells that live together, but do not form tissues or organs. Examples include some types of bacteria and algae.
* Cell culture: A group of cells grown in a laboratory setting.
* A spreadsheet with multiple rows and columns: In this context, each cell is a single box on the sheet.
To understand what "more than one cell" refers to in a specific context, you need more information about the situation.
