Document Summary
The cell is the smallest structural and function unit capable of carrying out life processes. Cells are the living building blocks of all plants and animals organisms. The cell is the basic unit of life. An organism"s structure and function ultimately depend of the collective. Because of this continuity of life the cells of all organisms are fundamentally structural characteristics and functional capabilities of its cells similar in structure and function. Trillions of cells in the human body classified into ~200 cell types. This is based on specific variations in structure and function. Despite variations, cells still share many common features: plasma membrane, cytosol, nucleus. Thin membranous structure that encloses each cell. Composed mostly of lipid (fat) molecules (bilayer) Barrier separates the cell"s contents from its surroundings. Selectively control movement of molecules into and out of the cell. Houses the cells genetic material, dna (deoxyribo-nucleic acid) Serves as a genetic blueprint during cell replication.
