What is the basic unit of life?

The basic unit of life is the cell. This is because cells are the fundamental building blocks that make up all living organisms. They carry out essential life processes such as metabolism, growth, and reproduction. Each cell functions independently and can carry out the necessary functions to sustain life. Cells can form tissues, which combine to create organs, and multiple organs work together within an organism. Understanding the cell's role as the foundational unit of life is crucial in biology, as all life forms, from simple single-celled organisms to complex multicellular organisms like humans, rely on cells to exist and function.
