Cell Membrane

Vote for Me, The Border Security of the Cell


The cell membrane is the most important part of the cell because it controls the materials that come in and out of the cell. This is just like border security; they let only efficient materials in and harmful materials stay out.  Without the cell membrane any materials would be able to enter the cell including intruders, there would be no way to stop them from attacking the cell. The cell membrane stops the cell from crashing and becoming unresponsive because it stops any horrible cells from entering the cell and disrupting its function. Without the cell membrane we would probably all be dead because our trillions of cells would all be invaded with disease-filled cells and they would slowly destroy us.

  2. You go on to say that without the cell membrane, we would be dead because of foreign objects, such as virions, entering the cell. However you failed to realize that this is the case with many sorts of diseases. The cell membrane's receptors and the cell membrane itself allows viruses that are so deadly, such as the HIV virus, to enter it's membrane and cause the harm it does. Also, failure to produce proper proteins and receptors on the surface of the membrane are also the reasons many cells cannot bring vital material within the cell because these materials do not have the ability to be diffused within the cell.

    Next, cell membranes are entirely inefficient when it comes to balancing diffusion in high concentrations. If an animal cell is placed within an aqueous solution with salt, the water will rush within the cell because of the membrane's permeability and burst the cell. Talk about inefficient. Sadly, with this, the pumps on the membrane that work against the concentration gradient to allow a balanced sodium level inside and outside the cell do not work fast enough. Pop! Just like a balloon!

    Finally, the cell membrane is such a fragile membrane unlike the cell wall within plants and is susceptible to tears. Just an accident waiting to happen, unfortunately.

    3. Also, to continue onward with my comment - comes the question.. Who manufactures the cell's membrane? Well, my organelle is involved in the synthesis of phospholipids - ergo the main molecule that forms the cell membrane. Many of the proteins and receptors that are vital to the well being and survival of the cell are manufactured on the site of protein synthesis, my organelle. Where would you be without the Endoplasmic Reticulum?

  3. The cell wall provides the cell with extra support and protection, in addition to be used as a filtering mechanism. Without the cell wall, the plant would lose its rigid shape. Another major function of the cell wall is to act as a pressure vessel preventing a large amount of water from entering in the cell. The cell wall provides another layer of protection outside the cell membrane controlling what enters and leaves the cell. The wall is not as fragile as the cell membrane. Without another layer of protection, it is easier for viruses to enter the cell.

  4. Border security makes mistakes! The cell membrane could potentially let harmful materials into the cell without even knowing it. What happens then? Well, the cell would have to self-destruct (apoptosis), if the situation required it. Regardless, the mitochondria would provide the cell with the energy needed to remove the intruder, or begin apoptosis, and prevent a mutation in the cell. Therefore, the mitochondria is more important that the cell membrane.

  5. You claim that you are the only thing protecting all of us other organelles from the harmful diseases within a structure. However, all of us organelles in eukaryotic cells are membrane-bound anyways. Also, if you are the only thing dividing all of us organelles from diseases, how do some of the other cells become infected. It must be because you don't always do your job as well as you say you do.

    I, the mitochondria, have two membranes: an inner and outer one! I am so thankful for these membranes because when you fail to complete your job and let diseases into the cell, I will probably be the organelle that is protected longest. Even if the harmful diseases (that you let in) penetrate my outer-membrane, I still have the inner-membrane to make sure all of the materials inside of me, stay inside of me.

    Overall, I guess I am just thankful for my two membranes in case you fail to keep those pesky diseases out.

  6. Although I very much agree that the cell wall is a necessity for the survival of the cell, I do not believe that it should be considered as ''the most important organelle''. I am strongly for this because of the fact that you are simply present to maintain and insure that only good nutrients enter the cell. I on the other hand am the most important part of mitosis! I am the cause of you still being present today. In fact, I’m the cause of every one still being here and living here today. Without cell division, how would you duplicate? The answer to that is simple. You wouldn't!

    Without me your job would be useless because the cell would either explode or break down and die because of the size it will get and lack of proper function. Cell division is mandatory for reproduction, growth, and repair of all that is living.

    And what happens when you silly membranes make mistakes and allow harmful nutrients to the cell. One simple mistake like that causes you and me both our lives. On the other hand, I, the centriole would never make a mistake. Chromatins just love to be close to me. And for the ones that don’t like me or neglect to be attracted to my microtubules pull, I unlike you have somewhat of a backup plan which are my spindle fibers. They force the chromatin's closer to me.

    Just admit it. I’m more important.

  7. As Mikala said, the cell membrane could accidentally let in harmful materials that are going to effect the cell in a negative way. Also, in a plant cell a cell wall is present contributing to keeping these materials out. By having the cell wall it helps the cell membrane out, therefore giving the cell membrane an easier job. When the cell membrane allows unwanted materials to enter the cell such as viruses or other toxins, it could be very harmful to the cell.

    This is where the lysosomes come in. If a cell membrane made a mistake by allowing these materials in, the lysosomes would be able to break down these materials (viruses) and protect the cell from anything that will do damage to it. On top of all of this the lysosomes have many more jobs that include eliminating any worn out cell organelles and digest waste that is produced inside of the cell. Most organelles inside of a cell have membranes (membrane bound) therefore each organelle already has a membrane that is bringing in and out materials and protecting us from anything that is harmful to our organelle. Overall, I do not think that the cell wall is more important than the lysosomes because of the common mistakes a cell membrane can make.

  8. Sorry to break it to you, Cell Membrane, but you're actually not the star of the show here ... Without the proteins that I, the ribosome, create, it would not be physically possible to move materials in and out of the cell - thus leaving you without a function in the cell. Without me, there is no you! In all honesty, the cell membrane is more of a 'one-trick pony' and is better suited as one of the less important organelles in this cell. The ribosomes, however, are completely VITAL to life! I create the proteins in the cell, which then go on to do a variety of tasks around the cell. These tasks include reproduction, growth, creating DNA, fighting viruses, and MANY MORE! It doesn't get much more important than that!

    See you in the cell!
