    a) Human tooth: Dissecting Microscope
    The image that appears in a Dissecting Microscope is three dimensional. It is used for dissection to get a better look at the larger specimen. One cannot see individual cells because it has a low magnification but that is not required here.

    b) Human blood cell: Compound Light Microscope
    Compound Light microscope is the most commonly used microscope. One can view individual cells, even living ones through this microscope. It has a high magnification that is sufficient for viewing human blood cell.

    c) Mitochondrial membrane folding: TEM
    Examining mitochondrial membrane folding requires 10,000x plus magnification which is just not possible using Light Microscopes. Hence TEM (Transmission Electron Microscope ) is used which provides the required magnification. TEM has a high magnification and high resolution.

    d) Pollen grain surface structure: SEM
    The surface structure is examined using the scanning action of electrons. Scanning Electron Microscope (SEM) is used for this purpose. SEM use electron illumination. The image is seen in 3-D. It has high magnification and high resolution. The specimen is coated in gold and the electrons bounce off to give an exterior view of the specimen.
