Question

Prepare model of a cell using different eco-friendly materials.

Answer 1

Materials Needed

1. Base (Cell Boundary): Cardboard, coconut shell, or an old basket to act as the base of the cell. Clay or dough for shaping.
2. Cell Membrane: Use a soft rope, wool, or string to form the outer boundary.
3. Cytoplasm: Fill the base with colored rice, sand, shredded paper, or biodegradable foam.
4. Nucleus: A small ball of clay, dough, or a walnut shell for the nucleus. Use a colored bead or seed (like tamarind seed) for the nucleolus.
5. Mitochondria: Use dried beans (like kidney beans) or small twisted pieces of clay.
6. Chloroplasts (in Plant Cell): Green mung beans, lentils, or small green clay shapes.
7. Vacuole: A small pouch made from paper or fabric filled with cotton or grains.
8. Endoplasmic Reticulum: Pasta pieces (e.g., spaghetti or macaroni) or paper strips.
9. Golgi Apparatus: Layers of leaves, cardboard, or flattened clay.
10. Ribosomes: Small seeds like mustard seeds or beads.
11. Lysosomes: Small pieces of colored clay or beads.
12. Centrioles (in Animal Cell): Toothpicks or matchsticks.
13. Tools: Glue, scissors, eco-friendly paints, and markers for decoration.

Steps to Assemble

1. Prepare the Base:

   • Use cardboard or a similar eco-friendly material as the base for your cell.

2. Add the Cell Membrane:

   • Glue or arrange the string, wool, or rope around the edge to form the cell membrane.

3. Fill the Cytoplasm:

   • Spread sand, shredded paper, or colored rice inside the boundary.

4. Place the Organelles:

   • Position the nucleus (ball or walnut shell) at the center.
   • Arrange the other organelles (mitochondria, chloroplasts, etc.) as per their actual placement in a cell. Use glue to secure them.

5. Label the Parts:

   • Use paper or eco-friendly markers to create small flags or labels for each part of the cell.

6. Final Touches:

   • Paint or decorate the materials lightly to make the model more realistic and colorful.
