Match the type of microscopy on the left with the description provided below. There is one best match _____ scans the spectrum with a focused laser beam to obtain a series of two-dimensional optical sections which be used to a focused laser beam obtain a series of an scans be specimen with dimensions. The laser excites image of the specimen in illuminated point is captured a fluorescent dye molecule, and the emitted light from each illuminated point is captured through a pinhole and recorded by a detector. confocal transmission electron phase-contrast scanning electron Match the type of microscopy on left with the corresponding description below. There is one best match. _____ the provided has the ability to resolve as small as 2 nm. confocal transmission electron fluorescence scanning electron Match the type of microscopy on the left with the corresponding description provided below. There is one best match requires coating the sample with a thin layer of a heavy metal produce three-dimensional images of the surface of sample Confocal transmission electron scanning electron phase-contrast Indicate whether the following statements are true or False. The nucleus of an animal cell is round, small, and difficult to distinguish using light microscopy True False The cytosol is fairly empty, containing a limited a number of rapid movement via diffusion. True

Solution

1. Confocal microscopy -The confocal microscope uses a laser beam to illuminate a specimen, usually one that has been fluorescently stained.

2. Transmission electron Microscope- TEM has much higher resolution than SEM.

3.Scanning electron microscope. It requires the metal coating of the specimen to get a 3D image

4.False. Using a light mocroscope you can look the nucleus of a cell

5. True. the presesnce of plasma membrane canbe inferred by the well defined boundry of the cell

6. true. cytosol is the fliud with in the cell alo known as cytoplasmic matrix ( cytoplasm without cell orgenelle)
