Biology: Test Your Cells Knowledge! Quiz

What do you know about cells? Do you think you understand enough to pass this quiz? The cell is the fundamental structural, functional, and biological part of all known organisms. A cell is the smallest possible component of life. Cells are frequently called “the construction blocks of life. ” The analysis of cells is called cell biology. Take this quiz and test your knowledge about cells.
