What is the basic building block of life?

• A. Atom
• B. Molecule
• C. Cell
• D. Organ

Answer: (C)

Cells are the smallest unit that can carry out all the processes that define life. They can perform metabolism, respond to their environment, grow, and reproduce, which is why they form the building blocks of all organisms. Inside a cell, structures called organelles handle specific tasks to keep the cell alive. When cells group together, they form tissues, then organs, and finally entire organisms. Atoms are the tiny particles that make up molecules, and while molecules are essential components, they don’t carry out life on their own. An organ is a larger structure built from tissues and many cells, not the basic living unit.
