Adipocytes are fat cells, which specialize in storing energy as fat.
There are lots of people out there who make their new year’s resolutions to loose weight. It is no surprising that these fat cells are scared of shrinking or disappearing completely.
To analyze cells in the blood sometimes the red blood cells (RBCs) need to be removed. This can be done by lysing the cells. There are various RBC lysis buffers available that do just that.

Epithelial cells form a layer that line several organs of the body providing a barrier to the outside world. In other words, the epithelial cells help to protect or enclose the organs.
Epithelial cells are held together by tight junctions, which form a virtually impermeable barrier to prevent leakage of fluid (including molecules and ions) across the cell layer, so materials must actually enter the cells in order to pass through the tissue.

Plant cells and animal cells are both eukaryotic cells. Even though they have a lot of similarities they are different. One of the differences that this cartoon is playing on is the ability of plant cells to generate their own glucose. This is made possible due to the chloroplasts. Animal cells on the other hand need to get their glucose from an outside source.
Just to show how cool the chloroplasts look like below is a video by Microscopic World showing cytoplasmic streaming in plant cells.
