When you look at yourself in the mirror, it’s hard to imagine that you are made up of cells, trillions of them, working together. Though each cell in your body contains your entire genetic code — your DNA — in its nucleus, it is also specialized to carry out specific tasks. Different systems and parts have different types of cells: skin cells, blood cells, muscle cells, and nerve cells, to name a few.
In cellular biology and histology, you’ll study how cells work, both on their own and as part of larger structures, like organs and tissues. You’ll look at the parts within the cell and see how cells combine to form larger structures.
