Creating a plant cell model from is a fun and creative way to teach the different parts of a plant cell. While the cake itself represents the plant cell, you can use different icing colours and decorations to represent the organelles within the cell.
Things you need
- Diagram of plant cell
- Square or rectangular cake pan
- Green frosting
- Nonpareil sprinkles
- Coloured frosting and piping bags
Bake a square or rectangular cake. Using a basic 22.5 by 32.5 cm (9 by 13 inch) cake pan will work well and is the simplest.
Ice the cake with green icing after the cake has cooled. While individual plant cells are not necessarily green (it is the chlorophyll within the cells that is actually green) it will bring a more realistic appearance to the cake.
Create organelles on the cake using different coloured icing. Using the plant cell diagram as a reference, create large circular vacuoles (which hold water) out of light blue icing. Create a single smaller circle for the nucleus of the cell. The golgi apparatus and the endoplasmic reticulum can be made with frosting loaded into a piping bag with a tip that creates a thin straight line. Curve the line back and forth upon itself to create these organelles. Create a square outline on the top of the cake for the cell wall, just to the inside of the top border (you can also use thin strands of liquorice for this).
Create additional organelles with candies. Mitochondria are shaped like jelly beans, so these are a good choice for these organelles. Create ribosomes, which are responsible for protein production, by sprinkling the endoplasmic reticulum with darkly coloured nonpareil sprinkles. Leave some endoplasmic reticulum nonpareil-free to distinguish between rough and smooth varieties. Use green sugar-coated chocolates or gumdrops to represent the chloroplasts, which contain plant pigments like chlorophyll.
