There is no such thing as a typical cell. . . Although they may look different under the microscope, most cells share common chemical and structural features. In humans, there are about 200 different types of cells, and within those cells, there are about 20 different types of structures or organelles.

What is the typical lifespan of a cell?

On average, every cell in your body 7 to 10 years. But these numbers hide huge differences in the lifespans of different organs of the body. While neutrophils (a type of white blood cell) may only last two days, the cells in the middle of the eye’s lens will last a lifetime.

What is the structure of a typical cell?

A cell consists of three parts: cell membrane, nucleus, and, in between, the cytoplasm. Within the cytoplasm are intricate arrangements of fine fibers and hundreds or even thousands of tiny but distinct structures called organelles.
