Question

The figures of cork cells as seen by Robert Hooke were published in the book
A. Origin of species
B. Species Plantarum
C. Genera Plantarum
D. Micrographia

Answer 1

Hint: The book published by Robert Hooke was published in January 1665. Hooke's 1665 book contains the earliest knowledge of an observed microorganism which was a microfungus Mucor. Also, Robert Hooke was the first one to coin the term Cell in the thin-sliced cork.

Complete answer:
1. The book described the microscopic view of plants and animals. Robert Hooke observed a thin slice of cork under a magnifying device. Cork is nothing but a bark of a tree. Under the microscope, he noticed that the slice of cork showed small boxes or compartments. He described them as honeycomb-like in appearance.
2. He also observed that these small boxes or compartments were separated by a wall or partition.
3. He termed these boxes as cells. These cells were dead cells because observation of living cells requires improved microscopes which were not available at that time.
4. Soon after Hooke's observation, many other scientists like van Leeuwenhoek observed many other living cells. After 1950, the invention of the electron microscope allowed them to view various other minute structures of the cell-like mitochondria, nucleus, ribosomes, etc.
5. After Schwann and Schleiden theory and Virchow seeing cell division, cell theory was developed. According to which all organisms are made up of cells and all cells come from the division of previous cells.

So, the correct answer is “Option D Micrographia”.

Note:
1. Charles Darwin wrote about the origin of a species. This scientific literature was published on 24 November 1859. The origin of a species gave a theory that over a course of a generation, the population evolves through natural selection.
2. Species Plantarum is written by Carl Linnaeus and published in the year 1753. The book species Plantarum has a list of every species of plant known at that time.
The fifth edition of the book Species Plantarum is Genera Plantarum.
