Advances in microscopy: now we have electron microscopy, to prepare the specimens we have to coat the specimen with a tiny sheet of gold, or you can cut the samples into very thing slices. Friday, january 9, 2015: we also have fluorescence microscopy, track the proteins within a localized cell by taking them with an antibody with a. Orescent tag: then they will glow with certain wavelengths, finally we have time-lapsed recordings, we are able to to long term imaging, 1d, 2d, 3d environment. The importance of cell components and overall function: use of electron microscopy, allows us to look at images and identify wether it is plant or animal.
