In 1665, the English scientist Robert Hooke published a book called Micrographia. The book contained detailed drawings of all the organisms and materials. Hooke had examined under his microscope. The book was a best seller at the time. One of the drawings shows a thin layer of cork, the bark from a cork tree. Hooke commented that the cork was divided into many pores or cells that looked like small rooms. In fact, this was the first drawing of plant cells.How were Hookes observations valuable int he development of cell theory?

In 1665, the English scientist Robert Hooke published a book called Micrographia. The book contained detailed drawings of all the organisms and materials. Hooke had examined under his microscope. The book was a best seller at the time. One of the drawings shows a thin layer of cork, the bark from a cork tree. Hooke commented that the cork was divided into many “pores” or “cells” that looked like small rooms. In fact, this was the first drawing of plant cells.How were Hooke’s observations valuable int he development of cell theory?

A	Hooke’s observations of the “cells” in cork bark helped lead to the concept that all living things are made of cells.
B	Hooke’s observations of the “pores” in a thin layer of cork helped lead to the concept that the outer layer of a cell has many pores or holes in it.
C	Hooke’s observations on the “cells” in cork bark helped lead to the concept that nonliving things such as rocks and sand are made of cells.
D	Hooke’s observations on the “cells” in cork bark helped head to the concept that trees are not living organisms.

Explanation:

Detailed explanation-1: -Micrographia by Robert Hooke, 1665.

Detailed explanation-2: -Robert Hook refined the design of the compound microscope around 1665 and published a book titled Micrographia which illustrated his findings using the instrument.

Detailed explanation-3: -English scientist Robert Hooke published Micrographia in 1665. In it, he illustrated the smallest complete parts of an organism, which he called cells. In 1665, Robert Hooke published Micrographia, a book filled with drawings and descriptions of the organisms he viewed under the recently invented microscope.

Detailed explanation-4: -His work is famous for the study of cork cells. In 1665, Robert Hooke wrote a book Micrographia on some physiological descriptions of minutiae made by magnifying glasses with observation and enquiries. The chapter which gave birth to cell biology is Observe XVII.
