how can make a model of animal cell
Answers
Answer:
You can make a cell model project from a variety of materials. Perhaps the best option is to use foods and food containers. For the cell membrane, you can use either a pie crust or a round clear (e.g., glass) baking dish. Your finished product will thus look like a cross-section of a cell, as often shown in diagrams. A light-colored gelatin makes an ideal cytoplasm because you can embed the "organelles" inside and still see them easily.
Explanation:
You will also want something with which to label your cell. Long toothpicks or popsicle sticks may do the trick. You could cut up pieces of paper to as actual labels, which you can affix to the toothpicks or sticks once you have written them out.
The Organelles
Try using pieces of candy or fruit of appropriate shapes for the organelles, taking care to use contrasting colors for ease of labeling. For example, mitochondria are roughly oval in shape, so you could use oval cookies or candy. The nucleus contains compressed chromosome strands, so cooked angel-hair pasta might suffice. The trick is staying faithful to whatever diagram you base your model on.
Animal Cell Project vs. Plant Cell Project
Note that an animal cell is distinct structurally and functionally from a plant cell, so a single project cannot cover both. A plant cell model would differ from an animal cell model in straightforward ways. Plant cells have cell walls, tend to be square in shape and have chloroplasts, which afford them their green color; animal cells are roundish and contain centrioles. But you can consider making a plant cell model once the animal cell model is complete, to further your overall understanding of biology.
Which Organelles to Include?
At a minimum, you will want to display a nucleus, some mitochondria, the endoplasmic reticuum with ribosomes attaches, Golgi bodies, centrioles and vacuoles. Try to gain a sense for how these are distributed within a cell physically and in what relative numbers. Chill the gelatin portion for about 90 minutes before adding the "organelles," and then return the model-in-progress to the refrigerator for about three more hours.
When the model is done, label the organelles using your toothpicks or sticks, getting the tips as close as you can to the actual element being labeled. How much detail you put on the paper attached to the label depends on the course level and other than that is really up to you.
