Explanation:
Answer:
All living things are made up of one or more cells.
Explanation:
The cell theory is a universal theory proposed by three scientists viz: Theodor Schwann, Mathias Scleiden, and Rudolf Virchow in the year 1838. These three scientists contributed to the cell theory and proposed the following:
1) All living things are composed of one or more cells
2) Cell is the basic and fundamental unit of life
3) New cells arise from pre-existing cells.
However, at an earlier date specifically 1665, an English scientist named Robert Hooke has discovered and coined the term "cells" in his published book by observing a piece of cork under a microscope. This Hooke's discovery of cells from a once living cork best supports the part of the cell theory that states that: All living things are made up of one or more cells.
