Correct Answer
A Robert Hooke
Model Answer
- Robert Hooke was a British scientist.
- He built a microscope that could magnify objects about 42 times.
- During the time he was studying a thin slice of a bottle cork under his microscope, he observed that the slice displayed a honeycomb-like pattern of tiny, box-like compartments separated by thick partitions.
- Hooke christened these compartments as 'cells'.
- Since cork is made of the bark of trees which is dead tissue, the cells discovered were dead with cellulose walls. Though the cells discovered were dead, but they led to the foundation of a major field in science called 'cytology'.
- Robert Hooke's findings were published in London in 1665 in his book called 'Micrographia'.
- The study of cells is termed 'Cytology' and this term was coined by Hertwig in 1892.
