In most cases, the part of a cell or tissue that we want to look at isn't naturally fluorescent, and instead must be labeled with a fluorescent dye or tag before it goes on the microscope.

Learn about cell biology and the different types of microscopes that allow us to observe cell structure and function.

All cells come from other cells. New cells are made through a process called cell division. During cell division, one cell grows and splits into two. Single cells are typically too small to be seen …

How does a plant's root look under the microscope? What cells will you find? How will the cells be arranged? Watch this video to learn more about the anatomy of the root.

White blood cells are larger than red blood cells, and unlike red blood cells, they have a normal nucleus and mitochondria. White blood cells come in five major types, and these are divided …

According to cell theory all cells must come from preexisting cells, but then how did the first cell come about, and more importantly, why can't that happen again?

Eukaryotic cells have a nucleus, a membrane-bound chamber where DNA is stored, while prokaryotic cells don't. This is the feature that formally separates the two groups.

Cell diagrams are models that show the parts that make up a cell. Cell diagrams are useful because they show details that are hard to see, even under a microscope.

An introduction to cells, including the history of their discovery and the development of cell theory.

This cell produces the boney matrix, releasing it outside of the cell. As a result of it's work, as well that of other osteocytes, they form the boney caves or spaces in which they reside, called …
