There’s an immense world of tiny stuff within us and around us—but how do we know about it? In this episode of Crash Course Biology, we’ll discover how we see what we can’t see, thanks to the help of centuries-old tools and more recent...

Microscopes are great for studying tiny things, but they have limits. Luckily, scientists have found a way to make tiny things larger, and it involves a chemical you can find in diapers.

After completing a fairly extensive survey of bacterial and viral pathogens, it's time to learn about some other more general microbiology concepts. What better place to start than the indispensable tool of the microbiologist, the...

It explains the basic principle of working of a compound microscope and lists various types of microscopes used to view biological material.

In this section, I talk about the history of the cell theory, what the cell theory is, the 2 types of microscopes and the 2 basic cell types.

The video discusses the steps required to use a light microscope to observe and obtain a magnified and focused image of a group of cells. The presenter explains the common features of all light microscopes, such as the eyepiece and the...

Introduction to the main staining methods used in histology.

This video provides a lecture presentation on using the light microscope. It begins by explaining what a light microscope is and how it produces a magnified image. The video then shows how to prepare a slide of onion cells and view them...

This video provides an explanation of how the degree of magnification in a microscope is dependent on the type of microscope used. The concept of magnification is defined, and the equation for calculating magnification is introduced. Two...

Cardiac muscle tissue is found in the myocardium and is responsible for the contraction of the heart.

Now that we know a bit about the history of microscopy, let's dig into the first form that existed, light microscopy. This is the form that is familiar to most of us, as the microscopes we all looked through in high school biology class...

Students will learn about the discovery of cells, the development of the cell theory, and the differences between animal cells and plant cells, Animations illustrate the different parts of a cell. Other terminology includes: organelles,...
