How to Build 3D Models of Animal and Plant Cells. Every student in a junior high or high school science class has had to learn about the structures of living cells at some time or another. Perhaps you are enzymes in plant and animal cells recently taken your turn, learning about the various organelles of plant and animal cells. You must know the different organelles if you are going to model them. Vitally, you must understand their shape.
The colors usually given to the different cell components in text books are used for contrast and usually bear no resemblance to reality, so in that instance you can be creative. But you must develop the correct shapes in order to model them. It is also important to know how the various cell structures relate to one another. You must understand this fact as you are creating your model. Know the differences between plant and animal cells. Develop a concept for your model. Will your model be a transparent representation, with the cell components suspended in a see-through material? Will it instead be a cutaway model, giving the appearance of a cell that has been cut in half but containing organelles that provide a three-dimensional appearance? The first option is a fully three-dimensional representation of a cell, with all of the organelles suspended in clear gelatin.
The second option involves using craft materials to construct a cut-away model that shows a cell with a section removed to facilitate viewing. Think about the materials you would use. The materials will obviously vary depending on the type of model you have decided to construct. It is easiest to use items that already have the general shape of the object you are modeling–say, something roughly circular for a cell nucleus. Of course, many of the organelles are shaped so strangely that it may be impossible to find something that already has the same appearance. In this case you should think of materials that are flexible and can be fitted to whatever appearance you need. Will your 3D model be edible? What types of colors will you use for each organelle?
Never lose sight of the vital elements that must be represented in this project, but the form of your model does each enzyme catalyzes only one type of reaction always have to limit its style and creativity. Get the materials to make your cell parts. You’ll be making the parts of your cell out of various food and kitchen items. Clear gelatin will work as the cytoplasm.
If you are simply going for authenticity, non-flavored gelatin would work perfectly well. If you have decided to go edible, choose a variety that won’t be so darkly colored as to obscure the model organelles you place inside. For the nucleus, nucleolus and nuclear membrane: Purchase a pitted fruit, such as a plum or peach. The pit is the nucleolus, the fruit is the nucleus, and the skin is the nuclear membrane. Centrosomes are supposed to be spiky, try putting bits of toothpick through a gumdrop or other small gummy item. Model the Golgi apparatus using cut-out why do enzymes lower activation energy for a reaction of cardboard, wafers, crackers, sliced bananas or, perhaps best yet, a fruit roll-up stacked like an accordion.
