What is the basic unit of structure and function of life?

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

Answer: (C)

The cell is the basic unit of structure and function in living organisms. It is the smallest unit that can carry out all the activities that define life, such as metabolism, growth, response to stimuli, and reproduction. Inside a cell, structures like the membrane, cytoplasm, and organelles work together to carry out these processes, all governed by the cell’s genetic material. Molecules are the building blocks that make up cells, but they aren’t capable of functioning as life on their own. Tissues are groups of similar cells working together to perform a common function, and organs are made of multiple tissues coordinating to carry out more complex tasks. So, the cell stands out as the essential unit that initiates and sustains life.
