Study Notes
Cellular Structure and Function
- The cell is the smallest structural and functional unit capable of carrying out life processes.
- The plasma membrane's function is to regulate what enters and leaves the cell, providing a barrier between the cell's internal environment and the external environment.
- The nucleus' function is to store genetic information and control cell growth and division.
The Basic Unit of Life
- The cell is the basic unit of life, meaning that it is the most basic building block of life.
