Question

John wants to look at cells from the root of a young plant under the microscope. John cuts the tip off a root and puts it on a microscope slide. He adds two drops of iodine solution to stain the cells. He crushes the root by placing a plastic coverslip on top of it and pushing down on the coverslip gently with the eraser on his pencil.
a) SUGGEST ONE REASON WHY JOHN USES A PLASTIC COVERSLIP INSTEAD OF A GLASS ONE.

b) WHY DOES JOHN NEED TO STAIN THE CELLS?

Answer 1

B) it's easier to see the cellular parts such as the nucleus. For A) I'm inferencing this way the cover doesn't get smudge by the eraser
