Structure and function.

Explanation:

The cell is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.

Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Most plant and animal cells are only visible under a microscope, with dimensions between 1 and 100 micrometres. Organisms can be classified as unicellular or multicellular. Most unicellular organisms are classed as microorganisms.

Fun fact about cells: Scientists concluded that the average human body contains approximately 37.2 trillion cells!
