The cell is called the structural and functional unit of life as it is the smallest unit responsible for life processes. The cells are biological, functional, and structural units of all living beings that can independently replicate themselves. Therefore, they are called the biological block of life.

The cell is the most crucial body-forming unit. All the organs in a body are made up of cells. They multiply and divide to form new gametes and organs too. Below you can find the reasons why a cell is called the structural and functional unit of life.

Cell as the Unit of Life

Cells are called the structural and functional unit of life as all living things are made up of cells. They are important in performing numerous life processes which are necessary for sustaining life. The cells provide form and structure, process nutrients, and convert them into usable energy. The specialized cells in multicellular organisms perform specific functions.

Therefore, the cell is called the structural and functional unit of life as living things are made of cells, and they are important for sustaining life, converting nutrients to usable energy, and performing specific functions.

Examples of Cells in the Human Body

The human body has a diverse range of cells that perform different functions. A few examples of cells in the human body are as follows:

  • Blood has RBCs or Red Blood Cells that are basically tasked with transporting carbon dioxide and oxygen.
  • A photoreceptor cell is a specialized cell that is found in the eyes. This cell is tasked to convert light to signals which are capable of influencing biological processes.
  • Neurons or Nerve cells transmit electrical signals in the nervous system.
  • Muscle cells are responsible for contraction and movement in the body.

Summary:

Why is the Cell Called a Structural and Functional Unit of Life?

The cell is called the structural and functional unit of life as they are the smallest entities that exhibit the characteristics of life. All organisms, from simple unicellular organisms like bacteria to complex multicellular organisms like plants and animals, are composed of cells. A cell embodies the basic structural, organizational, and functional principles that underlie all living organisms.
