The structural and functional unit of life is:
a. A cell
b. An organ
c. The organism
d. A molecule

검증된 단계별 안내

Understand the question is asking for the basic unit that serves both structural and functional roles in living organisms.

Recall that in biology, the cell is known as the fundamental unit of life because it carries out all necessary functions to sustain life and forms the building blocks of all living things.

Consider the other options: an organ is made up of tissues, an organism is a complete living being, and a molecule is a chemical structure, not a living unit.

Recognize that the cell is the smallest unit capable of performing all life processes, such as metabolism, growth, and reproduction.

Conclude that the correct answer is the cell, as it is the structural and functional unit of life.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cell as the Structural Unit of Life

The cell is considered the basic structural unit of all living organisms. It forms the building blocks of life, providing the framework for tissues and organs. Every living thing is composed of one or more cells, which maintain the organism's structure.

Cell as the Functional Unit of Life

Cells perform essential life functions such as metabolism, energy production, and reproduction. They carry out biochemical processes necessary for survival, making them the fundamental functional units in biology.

Hierarchy of Biological Organization

Biological systems are organized hierarchically from molecules to cells, tissues, organs, and organisms. Understanding this hierarchy helps distinguish why cells, not organs or molecules, are the basic units of life.
