Question

What does cell theory state?

• A. Cell is a basic unit of life
• B. Cell is an over-crowded unit
• C. Cell is important only for reproduction
• D. None of the above

Answer 1

The correct option is A Cell is a basic unit of life

• Cell theory states that the cell is the fundamental unit of life. All living things are composed of one or more cells or the secreted products of those cells (e.g., shells, hairs, and nails, etc.).
• All cells arise from other cells through cell division. In multi-cellular organisms, every cell in the organism's body derives ultimately from a single cell in a fertilized egg.
  

So, the correct answer is option A.
