Creating a cellular model has been a particularly challenging task of systems biology and mathematical biology. It involves developing efficient algorithms , data structures , visualization and communication tools to orchestrate the integration of large quantities of biological data with the goal of computer modeling. It is also directly associated with bioinformatics , computational biology and Artificial life. It involves the use of computer simulations of the many cellular subsystems such as the networks of metabolites and enzymes which comprise metabolism , signal transduction pathways and gene regulatory networks to both analyze and visualize the complex connections of these cellular processes. The eukaryotic cell cycle is very complex and is one of the most studied topics, since its misregulation leads to cancers.
You could use some clay and shape it to make your cell parts, or you can get some some items that are similar-looking to the parts and use that instead.

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.

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. Most of the cells range in size between 1 and micrometers and are only visible with the help of a microscope. 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.
Wait until the gelatin is almost set, about an hour. 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 You can get most of these at any craft store, or even a local supermarket. Not Helpful 14 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 34 Helpful You could use some clay and shape it to make your cell parts, or you can get some some items that are similar-looking to the parts and use that instead. 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. Not Helpful 13 Helpful You could use clear gelatin, or if you are really ambitious, ice boil the water for clear ice and pour it in layers.
RNA is thought to be the earliest self-replicating molecule, as it is capable of both storing genetic information and catalyzing chemical reactions see RNA world hypothesis , but some other entity with the potential to self-replicate could have preceded RNA, such as clay or peptide nucleic acid. Let the cake cool completely and then remove it from the pan. Method 3. Gather your ingredients. 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.

Creating a cellular model has been a particularly challenging task of systems biology and mathematical biology. It involves developing efficient algorithms , data structures , visualization and communication tools to orchestrate the integration of large quantities of biological data with the goal of computer modeling. It is also directly associated with bioinformatics , computational biology and Artificial life.
It involves the use of computer simulations of the many cellular subsystems such as the networks of metabolites and enzymes which comprise metabolism , signal transduction pathways and gene regulatory networks to both analyze and visualize the complex connections of these cellular processes. The eukaryotic cell cycle is very complex and is one of the most studied topics, since its misregulation leads to cancers.
It is possibly a good example of a mathematical model as it deals with simple calculus but gives valid results. Two research groups   have produced several models of the cell cycle simulating several organisms. They have recently produced a generic eukaryotic cell cycle model which can represent a particular eukaryote depending on the values of the parameters, demonstrating that the idiosyncrasies of the individual cell cycles are due to different protein concentrations and affinities, while the underlying mechanisms are conserved Csikasz-Nagy et al.
By means of a system of ordinary differential equations these models show the change in time dynamical system of the protein inside a single typical cell; this type of model is called a deterministic process whereas a model describing a statistical distribution of protein concentrations in a population of cells is called a stochastic process.
To obtain these equations an iterative series of steps must be done: first the several models and observations are combined to form a consensus diagram and the appropriate kinetic laws are chosen to write the differential equations, such as rate kinetics for stoichiometric reactions, Michaelis-Menten kinetics for enzyme substrate reactions and Goldbeter—Koshland kinetics for ultrasensitive transcription factors, afterwards the parameters of the equations rate constants, enzyme efficiency coefficients and Michaelis constants must be fitted to match observations; when they cannot be fitted the kinetic equation is revised and when that is not possible the wiring diagram is modified.
The parameters are fitted and validated using observations of both wild type and mutants, such as protein half-life and cell size. In order to fit the parameters the differential equations need to be studied.
This can be done either by simulation or by analysis. In a simulation, given a starting vector list of the values of the variables , the progression of the system is calculated by solving the equations at each time-frame in small increments.
In analysis, the properties of the equations are used to investigate the behavior of the system depending of the values of the parameters and variables. A system of differential equations can be represented as a vector field , where each vector described the change in concentration of two or more protein determining where and how fast the trajectory simulation is heading.
Vector fields can have several special points: a stable point , called a sink, that attracts in all directions forcing the concentrations to be at a certain value , an unstable point , either a source or a saddle point which repels forcing the concentrations to change away from a certain value , and a limit cycle, a closed trajectory towards which several trajectories spiral towards making the concentrations oscillate.
A better representation which can handle the large number of variables and parameters is called a bifurcation diagram bifurcation theory : the presence of these special steady-state points at certain values of a parameter e. In particular the S and M checkpoints are regulated by means of special bifurcations called a Hopf bifurcation and an infinite period bifurcation.
Cell Collective  is a modeling software that enables one to house dynamical biological data, build computational models, stimulate, break and recreate models. The development is led by Tomas Helikar  , a researcher within the field of computational biology. It is designed for biologists, students learning about computational biology, teachers focused on teaching life sciences, and researchers within the field of life science. The complexities of math and computer science are built into the backend and one can learn about the methods used for modeling biological species, but complex math equations, algorithms, programming are not required and hence won't impede model building.
The mathematical framework behind Cell Collective is based on a common qualitative discrete modeling technique where the regulatory mechanism of each node is described with a logical function [for more comprehensive information on logical modeling, see   ]. Model validation The model was constructed using local e. In other words, during the construction phase of the model, there was no attempt to determine the local interactions based on any other larger phenotypes or phenomena.
However, after the model was completed, verification of the accuracy of the model involved testing it for the ability to reproduce complex input—output phenomena that have been observed in the laboratory.
To do this, the T-cell model was simulated under a multitude of cellular conditions and analyzed in terms of input—output dose—response curves to determine whether the model behaves as expected, including various downstream effects as a result of activation of the TCR, G-protein-coupled receptor, cytokine, and integrin pathways.
The E-Cell Project  aims "to make precise whole cell simulation at the molecular level possible". CytoSolve - developed by V. Shiva Ayyadurai and C. Forbes Dewey Jr. In the July issue of Cell , a team led by Markus Covert at Stanford published the most complete computational model of a cell to date.
The model of the roughly gene Mycoplasma genitalium contains 28 algorithmically-independent components incorporating work from over sources. It accounts for interactions of the complete genome , transcriptome , proteome , and metabolome of the organism, marking a significant advancement for the field. Most attempts at modeling cell cycle processes have focused on the broad, complicated molecular interactions of many different chemicals, including several cyclin and cyclin-dependent kinase molecules as they correspond to the S , M , G1 and G2 phases of the cell cycle.
This model showed the ability to control totally functional cell division through regulation and manipulation only the one interaction, and even allowed researchers to skip phases through varying the concentration of CDK.
