<h3>What is Robert Hooke's Observation?</h3>
In 1665, Robert Hooke used a microscope to examine a tiny box-like empty cavities which are referred to as cork cells. He observed that the cork was made up of tiny units that looked like a honeycomb. He referred to them as cells, and he was the first to find a dead cell. This observation has a major contribution in the cell theory.
Hooke published his results under the title Micrographia, about his microscopic observations on several plant tissues. He is remembered as the coiner of the word “cell,” referring to the cavities he observed in thin slices of cork. The cork cells protect the tree from bacterial or fungal infection. It prevents water loss through the bark.
