What instrument helped scientist develop the cell theory?
As microscopes improved, so did the understanding of the human body. But the real breakthrough came from the creation of the electron microscope in 1931. The electron microscope was capable of creating magnifications of up to 2,000,000x.
How was the invention of the microscope led to the discovery of cells?
The microscope was first invented and used by Robert Hooke. He looked at slices of cork under the microscope and noticed that they look like the little rooms that monks used. These were called cells. And so came the term cells for what makes up tissues.
What scientist came up with the term cell after viewing cork cells with a crude microscope?
The term "cell" was coined by Robert Hooke in 1665. While using a crude microscope, he observed small box-like structures in a piece of cork and described them as cells, likening them to the cells of a monastery.
What kind of microscope would you use to look at skin cells?
Pre-1600: In the 11th century, the Arab Alhazan described the use and characteristics of glass lenses. Two hundred years later, the English natural philosopher Roger Bacon was familiar with lenses. Eyeglasses, however, were not invented until the late 1200s.1600s: In 1608 the telescope was invented, with Galileo improving upon it with his own models. Around 1600, the microscope was invented, possibly by Hans and Zacharias Jansen. Due to poor lens quality, the early compound microscopes (ones that used two lenses) could only magnify an object up to 20 or 30 times its normal size.The first big microscopy advances came in 1665, when Robert Hooke published theMicrographia, a collection of copper-plate illustrations of objects he had observed with his own compound microscope. He coined the term "cell" when looking at a piece of cork under 30x magnification.In the late 1660s, Antony van Leeuwenhoek began to grind his own lenses and make simple microscopes. Each microscope was really a powerful magnifying glass rather than a compound microscope. Leeuwenhoek's hand-ground lenses could magnify an object up to 200 times! He observed animal and plant tissue, sperm cells and blood cells, minerals, fossils, and much more. He also discovered nematodes and rotifers (microscopic animals), and he discovered bacteria while looking at samples of plaque from his own and others' teeth.1700-1800s: Not much change in the basic microscope design occurred, but better lenses were crafted (using purer glass and different shapes) to solve problems like color distortion and poor image resolution. In the late 1800s, Ernst Abbe discovered that oil-immersion lenses prevented light distortion at highest magnification power. These are still used today on 1000x-objectivemicroscopes.1900s till now: In 1931, a pair of German scientists invented the electron microscope. This kind of microscope directs a beam of speeded-up electrons at a cell sample; as the electrons are absorbed or scattered by different parts of the cell, they form an image that can be captured by an electron-sensitive photo plate. This model enables scientists to view extremely small parts, magnified as much as one million times. (Check out these electron microscope images to see what it looks like.) The only drawback is that living cells can't be observed with electron microscopes. However, compound microscopes are being improved with digital and other new technology, making microscopy better for everyone from kids to lab microbiologists.
What other inventions came from the light bulb?
flashlight
Which came first the compound light microscope or the electron microscope?
The compound light microscope came first, dating back to the late 16th century. The electron microscope was developed much later in the early 20th century.
What came first in the study of living things?
Light microscope
What came first in scientific study of living things?
Light microscope
What major improvements came with the development of the scanning electron microscope?
images were three dimensional
Which came first the telephone or the electric light bulb?
The electric light bulb came first but was patented later that the telephone was.
Who used a microscope to observe slices of cork?
Robert Hook was first to look through a microscope to observe slices of cork. He described these as "boxes", later came to know as "cells".
What instrument helped scientist develop the cell theory?
As microscopes improved, so did the understanding of the human body. But the real breakthrough came from the creation of the electron microscope in 1931. The electron microscope was capable of creating magnifications of up to 2,000,000x.
What came first color or light?
Different colours may have existed prior to light. Although this is difficult to answer considering light may have been the first thing to exist as light is energy.

Why an electron have a negative charge?
Because the proton has a positive charge and neutral has a neutral!They need a negative and it came the electron!
Which scientist came up with the electron cloud?
Bohr-Rutherford
