Eukaryotic organisms rely on intracellular transport to position organelles and other components within their cells. Pigment cells provide an excellent model to study organelle transport as they specialize in the translocation of pigment granules in response to defined chemical signals. Pigment cells of lower vertebrates have traditionally been used as a model for these studies because these cells transport pigment organelles in a highly coordinated fashion, are easily cultured and transfected, are ideal for microsurgery, and are good for biochemical experiments, including in vitro analysis of organelle motility. Many important properties of organelle transport, for example, the requirement of two cytoskeletal filaments actin and microtubules , the motor proteins involved, and the mechanisms of their regulation and interactions, have been studied using pigment cells of lower vertebrates. Genetic studies of mouse melanocytes allowed the discovery of essential elements involved in organelle transport including the myosin-Va motor and its receptor and adaptor molecules on the organelle surface.

Not Helpful 20 Helpful Now that you've completed your project, the time has come to admire the sheer brilliance that is your finished 3D cell model. Cut it in half, but instead of putting clay on, you can use colorful markers and draw the organelles onto the Styrofoam. This page gave me ideas of how to make the project suitable for all of these levels. Here's a short list to get you thinking outside the box:.

It is also common to connect them to a PDE describing the diffusion of a chemical signaling molecule through the extracellular matrix , in order to account for cell-cell communication.
As such, cell-based models have been used to study processes ranging from embryogenesis  over epithelial morphogenesis  to tumour growth  and intestinal crypt dynamics .

Plant and animal cell centrosomes play similar roles in cell division, and both include collections of microtubules, but the plant cell centrosome is simpler and does not have centrioles.
During animal cell division, the centrioles replicate make new copies and the centrosome divides. The result is two centrosomes, each with its own pair of centrioles. The two centrosomes move to opposite ends of the nucleus, and from each centrosome, microtubules grow into a "spindle" which is responsible for separating replicated chromosomes into the two daughter cells.
There are three microtubules in each group. Microtubules and centrioles are part of the cytoskeleton. In the complete animal cell centrosome, the two centrioles are arranged such that one is perpendicular to the other. Golgi : The Golgi apparatus is a membrane-bound structure with a single membrane. It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell.
The stack of larger vesicles is surrounded by numerous smaller vesicles containing those packaged macromolecules. The enzymatic or hormonal contents of lysosomes, peroxisomes and secretory vesicles are packaged in membrane-bound vesicles at the periphery of the Golgi apparatus.
Lysosome : Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells. Peroxisome : Peroxisomes are membrane-bound packets of oxidative enzymes. In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration. In animal cells, peroxisomes protect the cell from its own production of toxic hydrogen peroxide.
As an example, white blood cells produce hydrogen peroxide to kill bacteria. The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.
Secretory Vesicle : Cell secretions - e. The secretory vesicles are then transported to the cell surface for release. Cell Membrane : Every cell is enclosed in a membrane, a double layer of phospholipids lipid bilayer. The exposed heads of the bilayer are "hydrophilic" water loving , meaning that they are compatible with water both within the cytosol and outside of the cell.
However, the hidden tails of the phosopholipids are "hydrophobic" water fearing , so the cell membrane acts as a protective barrier to the uncontrolled flow of water. Mitochondria : Mitochondria provide the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell. They are about the size of bacteria but may have different shapes depending on the cell type. Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane.
The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds cristae when viewed in cross-section. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food sugar is combined with oxygen to produce ATP - the primary energy source for the cell. Vacuole : A vacuole is a membrane-bound sac that plays roles in intracellular digestion and the release of cellular waste products.
In animal cells, vacuoles are generally small. Vacuoles tend to be large in plant cells and play several roles: storing nutrients and waste products, helping increase cell size during growth, and even acting much like lysosomes of animal cells.
The plant cell vacuole also regulates turgor pressure in the cell. Water collects in cell vacuoles, pressing outward against the cell wall and producing rigidity in the plant. Without sufficient water, turgor pressure drops and the plant wilts. In higher plant cells, that polysaccharide is usually cellulose.
Cancer stem cells: models and concepts.
Show less A cell model is a 3-dimensional structure showing the parts of a plant or an animal cell. You can make a model cell with things from around your house, or you can buy a few simple items to create a fun, educational project.
Then, use different colored clay to make the different cell parts, and attach them to the Styrofoam with toothpicks so they show the layout of your cell.
Finally, write labels for the cell parts, tape them to toothpicks, and stick the toothpicks in the Styrofoam where they belong. For information from our Science reviewer on how to make a model cell using Jello, scroll down! This article was co-authored by Bess Ruff. Categories: Biology Models. Learn why people trust wikiHow. Co-authored by Bess Ruff Updated: September 6, There are 15 references cited in this article, which can be found at the bottom of the page.
Method 1. Decide if you are making a plant cell or an animal cell. The shape of each cell is different, so depending on which type of cell you are building, you will need different materials. Research the parts of a plant cell.
You will need to understand what each cell part looks like and what job it performs for the plant cell.
Generally, plant cells are larger than animal cells and are rectangular or cube shaped. Research the parts of an animal cell. Unlike plant cells, animal cells do not have a cell wall. Animal cells can be various sizes and may have irregular shapes. Method 2. Gather your materials. Avoid using marshmallows, as they will float on top of the gelatin. Water A large plastic resealable bag A spoon A large bowl or container Access to a stovetop or microwave Access to a refrigerator.
Make the jello, but with less water than the instructions call for. This will make the jello stiffer and make it easier for the cell parts to stay in place. Dissolve the gelatin in the hot water and stir it carefully. Add the same amount of cold water to the mixture. If you are using unflavored jello, add fruit juice to the jello in place of water so the jello is a light, bright color.
The jello will represent the cytoplasm of the cell. Place your plastic bag inside a sturdy container, such as a large bowl or pan. Slowly pour the cooled gelatin into the bag. Make sure there is room in the bag for all the cell components that will be added in later. Seal the bag and put it in the refrigerator. Then, take the bag out of the refrigerator and open it. Add a variety of candies to the bag of jello to represent the parts of a cell.
Make sure you use candies that are the right color and shape to match the components of an actual cell. Consider using: Pink Mike and Ikes for the smooth endoplasmic reticulum. Blue Mike and Ikes for the mitochondria. Disc sprinkles for the ribosomes. Airheads for the rough endoplasmic reticulum. Sour gummy worms for the Golgi apparatus. Warheads for the vacuoles. Keep in mind that if you are making a plant cell, you will need to add in a cell membrane around the jello with candy such as Twizzlers or Pixie Sticks.
Create a key showing how the candies correspond with the parts of the cell. You may want to make a card with a piece of each candy glued to the card, or you can create labels by writing or typing the name of the cell part and attaching them to each candy.
Re seal the completed jello model and put it back in the refrigerator. This will allow the jello to fully set, creating a sturdy cell model. Feel to free to take a picture of the jello model, and then eat it! Method 3. Gather your ingredients. To make a cake model, you will need:  Cake mix, as well as the ingredients to make the mix Vanilla icing Food coloring of choice Various candies to represent the organelles, such as blue Mike and Ikes, pink Mike and Ikes, War Heads, Air Heads, sour gummy worms and sprinkles Toothpicks Labels.
Make the cake in a pan, based on the type of cell you are making. Use a round cake pan for an animal cell and a rectangular shaped cake pan for a plant cell. Follow the instructions on the package to bake the cake. You can also set aside a little of the batter to make one cupcake to represent the nucleus. Let the cake cool completely and then remove it from the pan. Place it on the cake board. Ice the cake. Dye the vanilla icing with the food dye, based on the color s you'd like to use to represent the cell components.
One option is to make separate colored icings to represent the different layers of the cell. For example, to make an animal cell, you could use yellow icing to represent the cytoplasm and red icing on the cupcake representing the nucleus. Place the candies on the cake to represent the organelle.
It may be helpful to have a printout or image of the cell to identify the cell components as you place them on the cake.
An example of good candies to use as components of an animal cell include:  Pink Mike and Ikes for the smooth endoplasmic reticulum. Stick toothpicks in the cake with labels for each part of the cell. Type up the labels on a computer. Cut out each label and attach them to the toothpicks with tape before placing them on the cake next to the applicable cell component.
Take pictures of the cake model, and then eat it! Method 4. To make a clay model of a cell, you'll need: A small or medium sized styrofoam ball. Cut the styrofoam ball in half. The size of the ball you use depends on how detailed you want to make the parts. Cover the flat side of the styrofoam ball with clay.
You can cover the entire half piece of Styrofoam with clay if you want to make the top of the ball a certain color. Make the different cell parts out of various colors of clay. It may be helpful to have a printout or image of the cell to ensure all of the cell components are represented. Be sure to use different colored clay for each component to distinguish them from each other. Add the components to the flat side of the styrofoam using toothpicks.
If you're making a plant cell, remember to add a cell wall to your model. Attach labels to the cell parts. You can do this by taping the labels to toothpicks or pins and sticking the pins into the styrofoam ball next to the applicable component. Its a ball that is made of white stuff called Styrofoam.
If you don't know what it is, go to to your nearest craft store, like Michael's, and ask for a Styrofoam ball. They might ask you for the size - just say medium or large. Yes No. Not Helpful 39 Helpful Not Helpful 13 Helpful Cut it in half, but instead of putting clay on, you can use colorful markers and draw the organelles onto the Styrofoam.

Not Helpful 37 Helpful Is it possible to make a model from pizza, and does anybody have any ideas? Maybe you could use food coloring on the dough and then make the toppings in the shape of the vacuole and whatever else you need.
You could use clear gelatin, or if you are really ambitious, ice boil the water for clear ice and pour it in layers. If you aren't planning on eating it, you could use clear wax or clear soap.
Not Helpful 16 Helpful If it is oven-bake or never-drying clay, just knead it in your hands for a bit. If it is air-drying, maybe wet your hands and knead it?
