Different Types of Cells

  There are lots of different types of cells. Each type of cell is different and performs a different function. In the human body, we have nerve cells which can be as long as from our feet to our spinal cord. Nerve cells help to transport messages around the body. We also have billions of tiny little brain cells and muscle cells which help us move around. There are many more cells in our body that help us to function and stay alive. Although there are lots of different cells, most of them can be divided into two main categories: prokaryotic and eukaryotic.
Prokaryotic Cells- The prokaryotic cell is a simple, small cell with no nucleus. Most bacteria are prokaryotic. There are three main parts to the prokaryotic cell: 1) the outside of the cell called the cell wall 2) the flagella which is like an appendage and can help the cell to move 3) the inside of the cell called the cytoplasm.

Eukaryotic Cells - these cells are a lot bigger and have a cell nucleus which houses the cell's DNA. These are the types of cells we find in plants and animals.
