Robert Hooke is credited with discovering cells while observing a piece of cork under a microscope in his book Micrographia, which he published in 1665, Hooke describes the small structures that he observed under the microscope. Which part of the cell theory is best supported by this discovery

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.
