Cell Theory & Microscopes

Front

What is the definition of Cell Theory?

Back

Cell Theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

What is a Compound Microscope?

Back

A Compound Microscope is an optical instrument that uses light to pass through an object and then through two or more lenses to magnify the image.

Front

What is the primary function of a microscope?

Back

The primary function of a microscope is to make small objects appear larger.

Front

What type of microscope uses electrons to create an image?

Back

Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) utilize electrons to create an image.

Front

What is the difference between a Light Microscope and an Electron Microscope?

Back

A Light Microscope uses visible light to magnify specimens, while an Electron Microscope uses a beam of electrons for higher resolution imaging.

Front

What are the building blocks of life?

Back

Cells are often referred to as the building blocks of life.

Front

What type of microscope requires light passing through a specimen?

Back

A Light Microscope requires light passing through a specimen.

Front

What is the role of lenses in a microscope?

Back

Lenses in a microscope focus and magnify the light or electrons to create a clear image of the specimen.

Front

What is the significance of the resolution in microscopy?

Back

Resolution is the ability to distinguish two close objects as separate; higher resolution allows for clearer and more detailed images.
