Question : Let us take a glass slide with a drop of water on it. Using an ice cream spoon gently scrape the inside surface of the cheek. Does any material get stuck on the spoon ? With the help of a needle we can transfer this material and spread it evenly on the glass slide kept ready for this. To colour the material we can put a drop of methylene blue solution on it.Now the material is ready for observation under microscope. Do not forget to put a cover-slip on it. Was there a darkly coloured, spherical or oval, dot-like structure near the centre of each cell ? Were there similar structures in onion peel cells?
