3.1: Introduction to the Human Body
3.2: The Basic Structural and Functional Unit of Life- The Cell
The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce. The macromolecules carbohydrates, proteins, lipids, and nucleic acids make up all of the structural and functional units of cells. In complex organisms, cells are organized into five levels so that an organism can conduct all basic processes associated with life.
