To create your plant cell, find a rectangular or square shoe box and paint or color it green. The shoe box will serve as the cell wall, a stiff structure that supports the cell. The next layer you will need to create is the cell membrane, which is a softer more flexible covering that is inside the cell wall. Choose a material such as plastic wrap, Ziploc bags or tissue paper, and use it to line the inside of your shoe box.
Inside the cell membrane is cytoplasm, a jelly-like substance that holds the parts of the cell together. A number of different substances can be used as cytoplasm. Green Jell-O works well, as the other organelles can be placed inside the Jell-O. Pour your Jell-O into your lined shoebox, and place other items inside before the Jell-O sets. Green hair gel is another option that has the same consistency as cytoplasm. Green sand, hand sanitizer and jelly will also work. As the green color of the plant cell comes from the chlorophyll in chloroplasts, rather than from the cytoplasm, you could also use a clear gel. Fill your shoebox with your cytoplasm and you will be ready to place your organelles in it.
Plant cells have several organelles, or cell structures. The nucleus is the largest organelle and controls all of the cell's activities. For the nucleus, find something large and round to place within or on top of your cytoplasm. You can use a toy ball, candy, a gum ball or a round fruit. You can also make your own nucleus with items such as clay, Play-Doh or a Styrofoam ball.
Plant cells have several other organelles. Recreate these parts by getting creative with items you can find in your kitchen. Try using macaroni noodles or seeds for the mitochonodria, which supply energy to the cell. The chloroplast is what gives the cell its green color, and lima beans work well for this part because of their corresponding color. Another organelle is the vacuole, which stores food, water and waste. Try using a small balloon filled with water, or a cotton ball. Create labels for each part by using a toothpick attached to paper with the cell part's name on it. Place the label next to your part, and you will have a simple three-dimensional representation of a plant cell.
