A student views some plant cells under a microscope.
Name the cellular structure that controls the movement of substances into and out of the cell.
Name one type of animal cell that does not contain a nucleus.
The image length of the cell from point A to point B is measured to be 48 mm.
The real length of the cell is 0.08 mm.
Calculate the magnification of the image. Use the equation:
magnification=size of imagereal size of object \text{magnification} = \frac{\text{size of image}}{\text{real size of object}} magnification=real size of objectsize of imageGive two advantages of using an electron microscope instead of a light microscope.
