Questions and Answers
Why is the cell considered the fundamental unit of life?
Why is the cell considered the fundamental unit of life?
- Because cells can only reproduce within a multicellular organism.
- Because all living organisms are made of multiple cells.
- Because multicellular organisms are more complex than unicellular organisms.
- Because even single-celled organisms demonstrate all essential life processes. (correct)

Study Notes
Cells: The Fundamental Unit of Life
- Cells are the basic units of life, like ourselves.
- They can grow, reproduce, process information, respond to stimuli, and perform numerous chemical reactions.
- Multicellular organisms contain billions to trillions of cells, arranged in complex structures.
- Many organisms are unicellular, composed of a single cell.
- Unicellular organisms are independent and exhibit all life's key properties.
- This demonstrates the cell as the fundamental unit of life.

Description
Cells are the basic units of life, capable of growth, reproduction, and response to stimuli. Multicellular organisms contain billions of cells in complex arrangements. Unicellular organisms demonstrate that a single cell exhibits all key properties of life.
