• A cell is a membrane-bound unit in biology that contains the essential components of life and is the building block of all living creatures.
• A single cell, such as a bacterium or yeast, is usually regarded as a whole organism.
• Cells acquire specialized functions as they mature.
• Even though cells are several times the size of atoms, they are still extremely small. Some of these single-celled organisms are spheres with a diameter of 0.2 m (1 m = about 0.000039 inch) and a total mass of 1014 gram—equal to 8,000,000,000 hydrogen atoms.
• A single mycoplasma microbe is around 400,000 times the size of a single human cell.
