10 Questions
What is the purpose of putting iodine solution on the onion peel?
To stain the cells and make the cell structures more visible
What would be observed if the iodine solution was not applied to the onion peel?
The cell structures would be less visible
Do all cells in the onion peel get evenly colored when iodine solution is applied?
No, different regions of cells get colored differentially
Apart from iodine solution, what other solution can be used to stain the cells of the onion peel?
Safranin solution
What is the function of the nuclear membrane in the nucleus?
It has pores for the transfer of material between the nucleus and cytoplasm

To control the transfer of material between the nucleus and cytoplasm
Study Notes
Iodine Solution and Onion Peel
- Iodine solution is used to stain the cells of the onion peel, making its cellular structures visible.
- Without iodine solution, the cellular structures of the onion peel would not be visible.
- Not all cells in the onion peel get evenly colored when iodine solution is applied, implying varying levels of starch presence.
Alternative Staining Solution
- Apart from iodine solution, other solutions can be used to stain the cells of the onion peel.
Nuclear Membrane Function
- The nuclear membrane, a double membrane structure, regulates the movement of molecules in and out of the nucleus.
Explore the effects of iodine solution on onion peel cells in this quiz. Learn about the purpose of using iodine solution, observe the differences in the peel with and without iodine, and understand how the solution affects the coloration of different cell regions based on their chemical composition.
