Answer 1

There are many discoveries that have changed the course of science and the world. Nikola Tesla’s discovery of alternating currents, for example, helped pave the way for widespread access to electricity, and Louis Pasteur’s discovery that heat and disinfectant could kill bacteria improved food safety and saved millions of lives. In 1655, the English scientist Robert Hookemade an observation that would change the study of biology forever. While examining a thin, dried section of cork tree with a crude light microscope, Hooke observed that he could plainly see the cork to be made up of tiny spaces surrounded by walls, much like a honeycomb, but that the spaces were irregular and shallow (Figure 1). Further, Hooke noted that these "little Boxes" were so numerous that there were "in a square Inch above a Million... and in a Cubick Inch, above twelve hundred Millions [sic]" (Hooke, 1655).

Figure 1: The cork described in Micrographia by Robert Hooke.

In his landmark book Micrographia, Hooke called these spaces "cells" because they resembled the small rooms monks lived in (cella in Latin). What Hooke’s samples were not able to reveal at the time, though, was that cells are not in fact empty. Though he was diligent in looking at his samples through different magnifications and with various light sources and angles, there were two major obstacles that stood in Hooke’s way of discovering subcellular structures. The first was that the microscope he was using at the time was still too low of a magnification to show that much was contained within the walls of the cells. The second: His samples were of cork – composed of long-dead cells, absent of any cytosol or organelles.

Answer 2

150 years

Step-by-step explanation:

Until 1665, people did not know what cells were, and neither did the function they performed. The discovery was made by Robert Hooke after analyzing cork cuts under the microscope. This scientist realized that the material was formed by small cavities, which he called cell (from the Latin cellula, which means small compartment).

150 years after this discovery, several studies have been conducted to look at cells in other living things. Mathias Schleiden and Theodor Schwann independently proposed after several studies that all living beings were made up of cells. This idea became the basis for allowing cell theory to be accepted.
