The microscope is important because biology mainly deals with the study of cells (and their contents), genes, and all organisms. Some organisms are so small that they can only be seen by using magnifications of ×2000−×25000 , which can only be achieved by a microscope. Cells are too small to be seen with the naked eye.
What is the importance of compound microscope?
Compound microscopes are used to view small samples that can not be identified with the naked eye. These samples are typically placed on a slide under the microscope. When using a stereo microscope, there is more room under the microscope for larger samples such as rocks or flowers and slides are not required.
Why is microscope an important instrument in the field of science?
Microscopes help the scientists to study the microorganisms, the cells, the crystalline structures, and the molecular structures, They are one of the most important diagnostic tools when the doctors examine the tissue samples.
What is compound microscope in biology?
A compound microscope is a microscope that uses multiple lenses to enlarge the image of a sample.
Why is the microscope an important tool in any scientific studies and researches?
The invention of the microscope allowed scientists to see cells, bacteria, and many other structures that are too small to be seen with the unaided eye. It gave them a direct view into the unseen world of the extremely tiny.
Why was the invention of a microscope important for the study of living beings?
All living organisms unicellular or multicellular are made up of cells. Microscope make it possible to see inside the cells that make up all living organisms. Without microscope we could not see or understand how life works. So the invention of microscope made it possible to see the basic component of life.
How is microscope essential in studying anatomy and physiology?
It reveals the microscopic structure of organs and tissues, elucidates the connection between structure and function, provides an understanding of the underlying chemistry through selective staining, and enables the comparison of normal and pathological tissues.
What is a compound microscope How does it work and what is it used for?
A compound microscope is an instrument that is used to view magnified images of small specimens on a glass slide. It can achieve higher levels of magnification than stereo or other low power microscopes and reduce chromatic aberration.
What is the compound microscope and how does it work?
A compound microscope uses two or more lenses to produce a magnified image of an object, known as a specimen, placed on a slide (a piece of glass) at the base. The microscope rests securely on a stand on a table. Daylight from the room (or from a bright lamp) shines in at the bottom.
Why a microscope is called a compound microscope?
The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective.
What are the important uses of a microscope in microbiology and parasitology?
The microscope is used in Urine Analysis to check for the presence of various types of crystals, and white blood cells, which could indicate a bladder infection. The microscope is used in Microbiology and Parasitology to identify different types of bacteria and parasites.
Do you think that the discovery of microscope helped the study of cell?
The invention of and subsequent refinements of the microscope led to the eventual ability to see cells. Robert Hooke was the first person to see evidence of cells in living things. In 1665, using a primitive microscope, he observed cell walls in a slice of cork.
Who is the father of Micro?
Antoni van Leeuwenhoek
Antoni van Leeuwenhoek (1632-1723), a cloth trader from Delft, is the founding father of microbiology. He used home-made microscopes to discover the invisible world of micro-organisms.

Why onion peel is kept in glycerine and covered by cover slip?
Answer: Explanation: Glycerine prevents the onion peel from drying up by cutting contact from the atmosphere while coverslip prevents the lens of the microscope to come in contact with the specimen.
What are three reasons why it is important to study the anatomy and physiology of the body?
- Fundamental Knowledge. Anatomy and Physiology provide basic knowledge about the human body.
- Theoretical & Practical Knowledge.
- Conditions of Emergencies.
- Tracking of Patient’s Health.
- Improves Medical & Clinical Skills.
- Quick Recognition & Analysis of the Cause of Illness.
What instrument is most important in the study of microscopic anatomy of the body?
A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles.
Which microscope is used in anatomy and physiology practical?
The Compound Microscope
The objective projects a magnified image into the body tube of the microscope, and then the eyepiece further magnifies the image projected by the objective. Thus, the compound microscope achieves a two-stage magnification.
How do we use a compound microscope to observe a specimen?
Compound Microscopes
Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip. Look through the eyepiece (1) and move the focus knob until the image comes into focus.
What is a compound microscope quizlet?
What is a compound microscope? –An instrument that uses light and two (or more) lenses to produce a larger image of an object. -Can magnify up to 1000 times. Proper handling.
What is compound microscope?
What is Compound Microscope? A microscope with a high resolution and uses two sets of lenses providing a 2-dimensional image of the sample. The term compound refers to the usage of more than one lens in the microscope. Also, the compound microscope is one of the types of optical microscopes.
Why are compound microscopes better than simple microscopes?
The compound microscope has a higher resolution compared to a simple microscope and uses a set of two lenses that can provide a two-dimensional image of the sample placed in the slide. The term compound used in the compound microscope defines itself as the use of more than one lens at least two lens minimum at a time.
