Robert Hooke, is a ground glass. He grinded the glass into a lens and discovered the cell!

In 1665, the English scientist Robter Hooke (1635-1703) used a homemade microscope to observe the thin sections of the cork, and found that the cork cork was composed of many honeycomb-like chambers, which he named cells. In 1838 and 1839, the Germans Schleiden and Schwann published the cell theory, confirming that the cell is the basic structural unit of all animals and plants, thus establishing the cell theory.

The English scholar Hooke discovered it in 1665 with a homemade microscope, and at that time it was a plant cell that was discovered.

Robert Hooke.
Robert Hooke (1635-1702) was an English physicist. He has made achievements in various fields such as astronomy, physics and optics, and is the discoverer of Hooke's law in physics. Hooke used a homemade microscope to observe creatures such as fleas, lice, and mold, and recorded the results of his observations and results in a book called Microspectroscopy, which was published in 1665.
The book also shows a picture of the cork he saw, with a number of honeycomb-shaped chambers, which he called "cells," which he thought at the time had a similar effect to animal blood vessels, in which fluid flowed to transport nutrients. In fact, all he observed at the time was the cell wall of the dead cells of the wood bolt. However, Hooke's depiction of Tanhui cells in the Micrograph is the first discovery and observation of early-tolerant biological cells in humans.

The cell was discovered by the English scientist Robert Hooke in 1665.
There is no universal definition of cells, but the common formulation is that cells are the basic structural and functional units of living organisms. It is known that all organisms except viruses are composed of cells, but the life activities of viruses must also be reflected in cells.
Generally speaking, most microorganisms such as bacteria and protozoa are composed of a single cell, that is, single-celled organisms, while higher plants and higher animals are multicellular organisms. Cells can be divided into two categories: prokaryotic cells and eukaryotic cells, but some people have proposed that they should be divided into three categories, that is, the original and prokaryotic cells should be separated as a parallel category. The discipline that studies cells is called cell biology.

Hello, the English scholar Hooke discovered in 1665 when he used a homemade microscope to observe cork flakes, he described the structure of plant cells for the first time, and for the first time borrowed the Latin word celler (chamber) to refer to the structure he observed. Later, the Dutch scholar Leeuwenhoek used a well-designed microscope to observe the living cells and protists of many plants and animals for the first time, and described the structure of the red blood cell nucleus of fish in 1674.
In the new textbook, based on the unanimously recognized research results of the archaeological community, we have made the following statement about the earliest known human beings in China: "Yuanmou Man lived about 1.7 million years ago, and it is the earliest known human in China. "However, since the 80s and 90s of the 20th century, there have been more advances and new discoveries in archaeology as to whether there were earlier human activities in our country. >>>More

Cancer cells refer to malignant tumor cells formed by normal cells that undergo genetic abnormalities under the action of various carcinogenic factors. Cancer cells** are different from normal cells, but they are fundamentally different from normal cells. First of all, normal cells are generally regular in shape and arranged in a neat arrangement. >>>More
