What technological design allowed scientists to determine differences in the internal structures of plants and animal cells?

Answer:

Different types of magnifying technology like light microscopy and electron microscopy helped scientist to determine differences in the internal structures of plant and animal cells.

Explanation:

Human eyes can only see up to 1 mm in range. Plants and animal cells are very small which cannot be seen by the naked eye. For this reason, microscopes have been used to see enlarged structures of cells with the help of a compound microscope or electron microscope.

Light microscope can only magnify up to 1000x time to see the details of the cell but electron microscopes can magnify up to 100,000x times. The cells to be examined for the internal structures are cut into fine slices with the help of ultramicrotome and visualized under transformation or scanning electron microscope.
