Which term refers to the basic unit of all living matter?

The term that refers to the basic unit of all living matter is "cell." Cells are the smallest structural and functional units of life, serving as the foundational building blocks for all living organisms. Each cell is capable of carrying out the essential processes of life, including metabolism, growth, and reproduction.

In the context of the biological hierarchy, tissues are composed of similar cells working together to perform specific functions, organs are made up of various tissues that collaborate to execute more complex tasks, and systems consist of multiple organs working in concert to maintain homeostasis and overall functionality of an organism. Understanding that the cell is the basic unit of life is crucial in fields such as biology and skin care, where knowledge of cellular functions can impact treatments and therapies.
