What is the function of cells in living organisms?

Cells are fundamental to the structure and function of all living organisms. They are often referred to as the basic units of life because they provide the necessary framework that supports biological processes. Each cell is specialized to perform specific functions, contributing to the overall activity of the organism.

In multicellular organisms, cells organize into tissues,then into organs, and ultimately systems, highlighting their role as the fundamental building blocks that contribute to the organism's anatomy and physiology. This organization allows for complex functions like metabolism, growth, and response to stimuli, which are all essential for life.

While energy storage, hormone production, and temperature regulation are important processes that occur within or among cells, they are not representative of the primary function of cells as the basic units of structure and function. The main takeaway is that cells themselves are the core components from which organisms develop and operate, making them essential to life.
