cell theory

In the past, scientists used simple microscopes to explore the tiny world invisible to the naked eye, unlocking a gateway to new discoveries and establishing the foundation for the revolutionary concept: the cell theory.

The cell theory

The brilliant minds who shaped the cell theory: Schleiden, Schwann, and Virchow These people are the one that came up with the cell theory. Schleiden: Discovered plants are made of cells. Schwann: Extended it to animals, saying they're cell-made too. Virchow: Completed the puzzle, stating cells come from existing cells.

The Big Rules of Cell TheoryAll living things are made of cells. Picture cells as the essential building blocks of life. They exist in all living organisms, making up the structure just like bricks in a building. Cells are like the tiny units that construct everything alive. Cells work together to build and shape living organisms. Each cell has its role, contributing to the overall structure and function of the organism. New cells come from existing ones. Visualize cells as if they were capable of creating copies of themselves. This process ensures that living things can grow and maintain their existence.

Discovering the Invisible with Better Microscopes Scientists used to have microscopes that showed things a bit blurry. Now, theyhave really powerful ones that show us cells super clearly. These advanced microscopes help us explore all the tiny details of cells.

Humans, just like all living organisms, are essentially constructed from cells.
