Cell Theory (noun)

Definition: Cell theory is a scientific idea in biology that states that all living things are made up of cells. Cells are the basic building blocks of life and are responsible for the functions of all organisms. This theory was proposed in 1838 by two scientists named Matthias Schleiden and Theodor Schwann.

Usage Instructions:

  • You can use it in discussions about biology, medicine, or any science-related topics.
Example Sentence:
  • "According to cell theory, every living organism, from the smallest bacteria to the largest whale, is composed of cells."
Advanced Usage:
  • In more advanced discussions, you might explore how cell theory has led to developments in fields like genetics, microbiology, and medicine.
