Detailed explanation-1: -Jorge looks through a microscope and observes the structures of cells on a microscope slide. He concludes that the cells he observes are eukaryotic cells. Which of these structures did Jorge most likely observe before making his conclusion? cells must perform many of the same types of functions as body systems do.
Detailed explanation-2: -You will know the cell you are looking at under the microscope is a eukaryote if you see a nucleus. This is the main distinguishing feature of eukaryotes and prokaryotes.
Detailed explanation-3: -Under the microscope, you should be able to see distinct masses that are rounded or oblong in shape and smaller than the nucleus. All eukaryotes have a plasma membrane and cytoplasm, and some (plants and fungi) have a cell wall.
Detailed explanation-4: -Prokaryotes are microscopic organisms belonging to the domains Bacteria and Archaea, which are two out of the three major domains of life. (Eukarya, the third, contains all eukaryotes, including animals, plants, and fungi.)
Detailed explanation-5: -Two types of electron microscopy-transmission and scanning-are widely used to study cells. In principle, transmission electron microscopy is similar to the observation of stained cells with the bright-field light microscope.
