What is the basic unit of life?

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

Answer: (B)

The basic unit of life is the cell. Cells are the smallest structural and functional units that can carry out all the processes necessary for life. They are the building blocks of all living organisms, whether they are unicellular (consisting of a single cell) or multicellular (composed of many cells). Cells perform essential functions such as metabolism, energy conversion, and reproduction. They contain the necessary machinery to maintain homeostasis and respond to their environment. Organisms are made up of one or more cells, and the interactions and functions of these cells give rise to tissues, organs, and systems. In contrast, atoms are the basic units of matter but do not exhibit the characteristics of life on their own. Tissues are comprised of groups of similar cells working together to perform a specific function, and organs are made up of different types of tissues that work together to carry out complex tasks. Each of these levels of biological organization depends on cells for their existence and function, affirming that the cell is indeed the fundamental unit of life.
