I'm only found in plant cells! I have a really important role in the plant cell. My job is to absorb all the light I can so that photosynthesis can be done. If the plant cell does not have photosynthesis occur then the plant has a chance of dying due to the oxygen the photosynthesis absorbs.
Without me, plants have a high chance of dying faster! They only have one other option which is to find something else to produce the oxygen to them so they do not die. Chloroplast has a big role in the plant cell. Even though it isn't in the animal also, it is still important!
Hello! It is I, the Centriole! There are many obvious and non-obvious reasons why I should be chosen as top cell, but before I tell you these reasons, let me inform you about myself. To begin I am located beside the nucleus and rough endoplasmic reticulum in the cell. A second fact you should know is that I am composed of nine sets of triplet microtubules. The reason why I have so many microtubules is because due to my amazing organization skills, it is my job to organize all of these microtubules during their assembly. I organize microtubules in mainly animal cells. Most plant cells lack centrioles all together because my organization is not essential in all eukaryotes. Now that you know a little more about me, I shall explain my essential role in the interphase stage of mitosis. As you know during the S and G2 phase DNA is replicated then continues to grow. My role during these two phases is to replicate to form two new centrosomes. These new centrosomes then go on opposite sides of the dividing nucleus and are both used as poles for the mitotic spindle. As you can see my role is essential during the interphase stage of mitosis and without me animal life would seize to exist. In conclusion, I should be nominated as top organelle for my perfect organization skills and role in animal life.

When you are thinking about who to vote for....remember ME, the nucleus! I am the most important organelle within the cell. I act as the brain of the cell, controlling movement, reproduction, structure, function, what comes in and out, growth and division of the cell. In addition, I hold all the cell’s DNA which contains genetic information about the cell used for activity. I’m like the brainiac maniac! I also contain the nucleolus where ribosomes (protein) are created. Its a no-brainer, I am definitely the most important organelle because without me, the rest of the cell would not survive.
The nucleus, always the center of everything.
...because the brain is a horrible thing to waste!
Is responsible for cytokinesis, cell movement, and the organization of the organelles within the cell.
WHY DO I CARE?
Oh.. you better. If you didn't have me, you wouldn't be able to have me as a "track" for the chromosomes to move during mitosis. Which means that if the chromosomes don't complete mitosis and you don't have the help from me to actually divide the cell during cytokinesis, then you wouldn't be here. Cells need to be able to divide or injuries would never heal, you would never grow, and lets be real here--you wouldn't exist!
OKAY..... What else???
-It provides movement and stability to the cell.
-The cytoskeleton consists of microtubules, actin filaments, and intermediate filaments.
Microtubules
- acts as a frame to determine cell shape.
- provides a set of "tracks" for cell organelles and vesicles to follow.
- forms the spindle fibers for separating chromosomes during mitosis.
Actin Filaments
-they associate with the proteins that control muscle contractions within the cell.
-carry out cellular movements including gliding, contraction, and cytokinesis.
Intermediate Filaments
-provide flexible strength for the cell.
SO WHEN YOU'RE VOTING, VOTE CYTOSKELETON!! AND REMEMBER--WITHOUT ME YOU WOULDN'T EXIST!!!
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.
The nucleus is a spherical organelle and is the control center of the cell. It is made up of the nucleolus, nucleoplasm, and a double membrane covered in nuclear pores.
The nucleus holds 6 feet of DNA within it. The nucleus directs all other parts of the cell. It is often considered the most important part of a cell. Without the nucleus' direction the other organelles wouldn't know what to do.
Although prokaryotic cells do not have a true nucleus they still have the components that make up the nucleus. It is just not within a nuclear membrane. All cells need the information stored in the nucleus. Some of the information is used for forming the cell, therefor without the nucleus the cell wouldn't be. The nucleus is also important for reproduction and cell metabolism. So, vote for nucleus. We will always put u before us.
We have a single cell membrane that carry digestive enzymes for breaking down poisonous materials in the cell. We are very well known for the production of bile acids that are important in the absorption of fats and fat-soluble vitamins like vitamins A and K and we also participate in the function of alcohol (ethanol) digestion that, because of that important role, your liver cells are going possess more peroxisomes than the majority of other cells in your body. And we don't stop there! We also play a role in cholesterol synthesis and the digestion of amino acids.
We Will Work Hard For You!
We work in a very specific way. Our enzymes attack complex molicules and break them down into smaller molicules which creates hydrogen peroxide, which we then break down into harmless water and oxygen. The oxygen can be used for the next digestive reaction.
We Don't Discriminate, We Love Everyone!
Not only are we in animal cells, but we are also in plant cells. You will find us in the glyoxylate cycle in germinating seeds, photoresperation in leaves, and fighting fungal penetration of plant cells.
