The Anatomy Of The Cell. Part 3 The Cell Membrane

Another Quick Recap

          If you have read the last two post, then you know that cells are the basic building blocks of all living things. Everything that is alive is made up of cells. And without Cells (the basic building blocks of all living things) you and I would not exist. We discussed the composition of the Cell (the basic building block of all living things). We began with the control center of the Cell (the basic building block of all living things), the Nucleus (the center of the cell).

          The Nucleus (the center of the cell) we learned, plays a very important part in Cell (the basic building blocks of all living things) reproduction. We learned that the Nucleus (the center of the cell) is where our DNA is located. Our DNA is what determines our eye color, our hair color, and our skin tone. Its what we call our genetic makeup. We also learned that the Cytoplasm (the watery fluid that surrounds the nucleus) contains nutrients that helps keep our Cells (the basic building blocks of all living things) healthy and aids in cell growth, reproduction, and self-repair. The Cytoplasm (the watery fluid that surrounds the nucleus)  also gives the cell it's shape.

          Once again let's visualize the raw egg. By now you know that the yellow yolk is the Nucleus (the center of the cell), and the clear, jelly like substance is the Cytoplasm (the watery fluid that surrounds the cell). 

The Cell Membrane

          Have you ever given much thought about why it is when you crack an egg into a pan to fry that it doesn't run all over the pan. Well there is a translucent film that encloses the egg and helps to keep the egg from losing it's shape. If you are  not careful when cracking an egg open, you may break the translucent film and the egg will run all over the pan. It's easier to see this film on a boiled egg. When you peel a boiled egg, you will sometimes see a thin white layer just underneath the egg shell. This is similar to the Cell Membrane.  The Cell Membrane encloses the Cell (the basic building block of all living things) and allows a substance to come in and go out of the Cell (the basic building block of all living things) The Cell Membrane (a translucent film that encloses the cell) protects the Cells (the basic building blocks of all living things) by acting as a barrier not only to keep substances from coming into the Cells (the basic building blocks of all living things) but the Cell Membrane (a translucent film that encloses the cell) also controls which substances may exit also.

              Remember, the Cytoplasm (the watery fluid that surrounds the nucleus) gives our Cells (the basic building blocks of all living things) their shape. But the Cell Membrane (a translucent film that encloses the cell) helps our Cells (the basic building blocks of all living things) keep their shape.

That's It In An Eggshell.

You've heard the old saying, " That's it in a nutshell. "Well here's the anatomy of a cell " In an eggshell." It is important for us to understand the cell, how it works, and what it needs to stay healthy. And when our cells are healthy, our body is healthy, and this adds up to healthy skin.
