Which term describes the smallest unit of life?

Explanation:
The basic unit that can perform the processes of life is the cell. This is rooted in cell theory, which says living organisms are made up of cells, and cells carry out the functions needed for life. A tissue is a group of similar cells working together, not the smallest unit. An organ is composed of tissues that collaborate to perform a specific task, and an organ system combines multiple organs to carry out broader functions. Because a cell is the smallest unit capable of carrying life processes, it best describes the smallest unit of life. Some organisms are unicellular, meaning a single cell handles all life activities.
