Weekly Summary 10/23

Currently, we are learning about microscopes and organelles. I have learned about who first discovered cells (Robert Hooke) and the different types of organelles in a cell. We are also learning about the differences between prokaryotic and eukaryotic cells. And, there are multiple types of microscopes. The light microscope and the magnifying glass are both used to magnify objects that are relatively large (though the light microscope can see with greater detail. However, the transmission and scanning microscopes, both types of electron microscopes can see in much greater detail. While the specimens have to be non-living, the scanning microscope can see the cell surface and the transmission can see inside the cell. We also learned about cell theory and began work on polypeptides.
