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.

In this video we will explore the microscopic structure of bone or the Harvesian system in depth. Discover the difference between spongy and compact bone, learn about the function of osteons, and …

One group, the granulocytes, includes neutrophils, eosinophils, and basophils, all of which have granules in their cytoplasm when stained and viewed on a microscope. The other group, the …

It's sometimes difficult to draw diagrams in biology! Remembering all those labels can be tricky! In this video, we're going to use a memory device to learn about the different parts of a dicot stem under a …

How a cell divides to make two genetically identical cells. Prophase, metaphase, anaphase, and telophase.

Label the parts of the animal cell. Click each dot on the image to select an answer.

So if we look at our muscle cells under a microscope, we'll see that they've got these striations on them, these bands, because remember, another name for skeletal muscle is striated skeletal muscle.

The colors come from fluorescent (light-producing) dyes that are used to label different molecules in the specimen. Scientists use fluorescence microscopes to observe the role of specific cell components in …

In telophase 1 and telophase 2, I am confused about the use of the word "haploid." They are both labeled "haploid," but they do not look the same.
