Dear student,                                                                                                                                                                      
Please find below the solution to the asked query    
The shell is a hard protective surface. When it is present it does not allow water to seep inside the egg. When this shell is removed water can easily move inside because the concentration of water is less inside the egg than outside, and thus causes swelling of the egg.
2. The process by which cell shrinks in hypertonic solution is called osmosis.
