Cell Structure and Functions

The cell is the basic structural, functional, and biological unit of all known living organisms. All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful. Living things may be single- celled or they may be very complex such as a human being. This book details on the cell structure and functions.
