What are the functions of cells in the human body?
What are the functions of cells in the human body?
They provide structure, take in nutrients, convert nutrients into energy, and carry out specialized functions.
What is the Classical / Unified Cell Theory?
What is the Classical / Unified Cell Theory?
All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Study Notes
Cell Basics
- The basic building blocks of all living things are cells.
- The human body is composed of trillions of cells.
- Cells provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Classical/Unified Cell Theory (1830s)
- All living organisms are composed of one or more cells.
- The cell is the basic unit of structure and organization in organisms.
- Cells arise from pre-existing cells.
History of Cell Discovery
- Anton Van Leeuwenhoek:
- Observed "animalcules" (protozoa) from pond water using a magnifying tool (1600s).
- Observed bacteria from his own dental scrapings.
- Observed RBC and sperm cells using a microscope.
- Built his own first compound microscope.
- Robert Hooke:
- Coined the term "cellulae" (later shortened to "cell") for the box-like structures he observed.
- Published Micrographia in 1665.
