What tools did Hooke discover?
Robert Hooke discovered cell in the year 1665. He observed cork cell in the bark of Spanish oak tree under a simple microscope and was able to see the empty structures surrounded by walls and named it a cell. He elucidated his observation in a book called “Micrographia”. Thus, the correct answer is option B.
What are the inventions of Robert Hooke?

Robert Hooke/Inventions
What is the greatest discovery of Robert Hooke that paved way in the improvement of microscope?
He most famously discovered the Law of Elasticity (or Hooke’s Law) and did a huge amount of work on microbiology (he published a famous book called Micrographia, which included sketches of various natural things under a microscope).
What materials did Robert Hooke use to make observations?
cork
… Hooke published, under the title Micrographia, the results of 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; his observation that living cells contain sap and other materials too often has…
What type of microscope did Robert Hooke invent?
compound microscope
Interested in learning more about the microscopic world, scientist Robert Hooke improved the design of the existing compound microscope in 1665. His microscope used three lenses and a stage light, which illuminated and enlarged the specimens.
Which 3 scientists directly developed the cell theory?
Credit for developing cell theory is usually given to three scientists: Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow. In 1839, Schwann and Schleiden suggested that cells were the basic unit of life.
What is the first invention of Robert Hooke?
In 1673, Hooke built the earliest Gregorian telescope, and then he observed the rotations of the planets Mars and Jupiter….Robert Hooke.

What are the 3 parts of the cell theory?
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within …
What type of scientist was Robert Hooke?
Robert Hooke, (born July 18 [July 28, New Style], 1635, Freshwater, Isle of Wight, England—died March 3, 1703, London), English physicist who discovered the law of elasticity, known as Hooke’s law, and who did research in a remarkable variety of fields.
How did Hooke improve the microscope?
Micrographia and Microscopy. In 1665, at age 30, Hooke published the first ever scientific bestseller: Micrographia. He further improved the microscope with lighting. He placed a water-lens beside the microscope to focus light from an oil-lamp on his specimens to illuminate them brightly.
What kind of inventions did Robert Hooke invent?
Hooke was the father of many inventions, considering his natural mechanical talents and interest within the scientific field. For example, in the year of 1658, working alongside Robert Boyle, Hooke invented an improved air pump (Burgan, 58).
When did John Hooke invent the barometer and thermometer?
Fascinated by seafaring and navigation, Hooke invented a depth sounder and water sampler. In September 1663, he began keeping daily weather records, hoping that would lead to reasonable weather predictions. He invented or improved all five basic meteorological instruments (the barometer, thermometer, hydroscope,…
What did Robert Hooke describe in his book Micrographia?
Hooke’s 1665 book Micrographia, describing observations with microscopes and telescopes, as well as original work in biology, contains the earliest of an observed microorganism, a microfungus Mucor. Hooke coined the term cell, suggesting plant structure’s resemblance to honeycomb cells.
How did Robert Hooke contribute to the theory of combustion?
Micrographia also contains Hooke’s, or perhaps Boyle and Hooke’s, ideas on combustion. Hooke’s experiments led him to conclude that combustion involves a substance that is mixed with air, a statement with which modern scientists would agree, but that was not understood widely, if at all, in the seventeenth century.
