A cell is the smallest unit of life that can replicate independently, and cells are often called the “Oh my god i’m made of smaller things". The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
