What is cell biology?
The study of cells of course...
This is my favorite area in biology, so fascinating! Cell biology is the study of cells, the smallest units of life. All living things contain cells. Cells exist in many different shapes and sizes, and each cell does specific functions that it is specialized to do. Red blood cells carry oxygen throughout the body, white blood cells control and regulate the immune system, and nerve cells (neurons) are responsible for coordinating the nervous system.
You will also need to learn about cells in plants, and some organisms are unicellular, or cells themselves, such as bacteria or other prokaryotes.
Hope this helps!
