- Modern cell theory has two basic tenets: All cells only come from other cells (the principle of biogenesis). Cells are the fundamental units of organisms. Today, these tenets are fundamental to our understanding of life on earth. However, modern cell theory grew out of the collective work of many scientists.

The English scientist Robert Hookefirst used the term “cells” in 1665 to describe the small chambers within cork that he observed under a microscope of his own design. To Hooke, thin sections of cork resembled “Honey-comb,” or “small Boxes or Bladders of Air.” He noted that each “Cavern, Bubble, or Cell” was distinct from the others (Figure 1). At ...
As scientists were making progress toward understanding the role of cells in plant and animal tissues, others were examining the structures within the cells themselves. In 1831, Scottish botanist Robert Brown (1773–1858) was the first to describe observations of nuclei, which he observed in plant cells. Then, in the early 1880s, German botanist And...
Prior to the discovery of microbes during the seventeenth century, other theories circulated about the origins of disease. For example, the ancient Greeks proposed the miasma theory, which held that disease originated from particles emanating from decomposing matter, such as that in sewage or cesspits. Such particles infected humans in close proxim...
1. Robert Hooke coined the term cell. He was inspired by monks rooms, which were called cells. 2. the modern cell theory is composed of three facts: a)all life is composed of one or more cells, b)a cell is a basic unit of life, and, c)all cells come from other cells. Hope this helps :)
