What else can I help you with?
What evidence is there that cells are made of organelles?
Electron microscopes show that animal and plant cells have organelles. The same microscopes show that bacteria do not have organelles.
What scientist improvement made the discovery of cells possible?
The invention of the microscope was a critical improvement that made the discovery of cells possible. In the 17th century, scientists like Robert Hooke and Antonie van Leeuwenhoek used microscopes to observe and study cells for the first time. This technological advancement allowed scientists to see and understand the building blocks of living organisms.
Microscopes led to the discovery that all organisms are?
Microscopes led to the discovery that all organisms are composed of cells. This fundamental tenet of biology, known as the cell theory, states that cells are the basic unit of structure and function in living organisms.
What made the first cells possible?
Chemical reactions were the basis of all cells but Stanely miller came up with an experiment which made cells possible.
What did the invention of the microscope made possible?
The invention of the microscope made it possible to observe and study tiny structures such as cells, microorganisms, and molecules that were previously invisible to the naked eye. This breakthrough revolutionized fields like biology, medicine, and materials science by providing a deeper understanding of the natural world at a microscopic level.
Type of microscopes made up of two or more lens?
Compound microscopes
Why did scientist take so long to conclude all living things are made of cells even with the help of a microscope?
The idea that all living things are made of cells took time to develop because early microscopes were not powerful enough to observe cells and their structures. Additionally, the concept of cells as the fundamental units of life was revolutionary and challenged existing beliefs at the time. It was through the cumulative efforts of various scientists and advances in microscopy that the cell theory was eventually established.
What scientist made over 500 simple microscopes?
The person who made over 500 microscopes was Anton van Leeuwenhoek.
What invention made it possible to see cells for the first time?
The invention of the microscope made it possible to see cells for the first time. The first compound microscope was developed in the late 16th century, allowing scientists to observe and study cells and microorganisms in greater detail.
What have modern microscopes made it possible to do?
The microscopes in our days make it easy to see the things that the naked eye can not. Light microscopes see objects down to about 500 nm. A nanometre = 1 metre/ 1000 000 000 Modern microscopes allow scientists to view individual cells but not see well the organelles in them. Electron microscopes are used to get details of organelles. An atom cannot be viewed through a microscope as it is about 1000 times less than the wavelength of visible light. An electron microscope can give the reflection of objects down to about a nanometre or slightly smaller. This is almost possible to view larger atoms.
What medical discoveries have been made using microscopes?
Microscopes have been instrumental in many medical discoveries, such as the identification of germs by Antonie van Leeuwenhoek, the discovery of blood cells by Marcello Malpighi, and the development of the first vaccines by Louis Pasteur. Microscopes also played a key role in better understanding diseases like tuberculosis and malaria.
What are the similarities between the microscopes made by Anton van Leeuwenhoek and the microscopes used nowadays?
both are bright field microscopes, and works on two lenses
