Which is the basic unit of structure and function in the body?

Explanation:
The cell is the basic unit of structure and function in the body. It is the smallest unit that can carry out all life processes, giving the body its form and enabling its activities. In humans, all tissues and organs are built from cells, and these cells contain specialized machinery—like mitochondria for energy production and a nucleus with DNA—that carries out the essential functions of life. Cells come together to form tissues, tissues form organs, and organs work together in systems to maintain health and homeostasis. While tissues, organs, and organelles are important, they exist because cells organize themselves into these structures.
