Cell Structure and Function Concepts

The video introduces the concept of cells, explaining that all living organisms are made up of one or more cells, which are the functional units of life. It describes the main parts of a cell: the cell membrane, cytoplasm, and nucleus, detailing their structures and functions. The video also covers the cell theory, formulated by Theodor Schwann and Matthias Schleiden, which states that all living things are composed of cells, cells are the basic units of life, and all cells come from pre-existing cells. The importance of cells in life processes is emphasized throughout.
