Nuclear Membrane Definition for Kids

Nuclear Membrane Definition for Kids


Take a few seconds to think about all of the tiny cells that you have all over your body and how fragile they are. When you get sick or if a disease is inside of your body, all of your little cells are in danger for being attacked and becoming sick as well. Without a nuclear membrane, your cells wouldn’t have any protection against illnesses and diseases. Understanding the importance of the nuclear membrane can help you to understand how your body is able to begin fighting off diseases.

1. Filtering Hundreds of Materials

One of the most important parts of the nuclear membrane is to protect your nuclei by filtering through hundreds of different materials on a daily basis. Imagine that your nuclei are little concerts that are happening throughout your body and the membrane is the body guard. The body guards will have to make sure that they check everyone’s I.D. and make sure that no one is bringing any weapons into the concert. In the event that the body guards found someone that would be dangerous to the venue and the people inside of the concert, they would have to kick them out, whereas people that aren’t a threat will be allowed into the club. This is basically the purpose of the nucleus membrane as it protects your nucleus from outside threats.

2. Different Membranes

When it comes to each nucleus in your system there are 2 different types of membranes, the outer and inner membrane. Each of these layers are known as lipid bilayers. In between the outer and inner membrane is where you’ll find the perinuclear space.

3. How Materials Are Transported

The best way to understand how materials move in and out of the nuclear membrane is to picture your skin. On your skin you have millions of tiny pores that are responsible for filtering out toxins through your sweat, so does the nuclear membrane. Each of the microscopic pores helps to pull healthy materials into the nucleus and they are responsible for filtering out unnecessary components that could be dangerous for the cell.

4. Proteins Inside of the Nuclear Membrane

You’re going to find that in every cell you will have a nuclear membrane and endoplasmic reticulum. Both of these pieces share a common border, which means that they might contain the same ingredients, such as proteins. The interesting part is that the outer part of the nuclear membrane has far more proteins than the endoplasmic reticulum.
