Concept six.1 To study cells, biologists use microscopes and the tools of biochemistry
one. The study of cells has been limited past their small size, and and then they were non seen and described
until 1665, when Robert Hooke first looked at dead cells from an oak tree. His gimmicky,
Anton van Leeuwenhoek, crafted lenses; and with the improvements in optical aids, a new globe
was opened. Magnification and resolving power limit what can be seen. Explain the deviation.
Magnification: Ratio of actual size to visible size
Resolving ability: Clarity
2. The evolution of electron microscopes has further opened our window on the cell and its
organelles. What is considered a major disadvantage of the electron microscopes?
Cell dies in the process
3. Study the electron micrographs in your text. Draw the different types of images obtained from:
scanning electron microscopy (SEM)
Detail of surface textures (What it looks similar)
transmission electron microscopy (TEM)
Detail of components (What makes up information technology)
4. In cell fractionation, whole cells are cleaved up in a blender, and this slurry is centrifuged several
times. Each time, smaller and smaller prison cell parts are isolated. This will isolate different organelles
and allow study of their biochemical activities. Which organelles are the smallest ones isolated in
this procedure?
Ribosomes
Concept six.2 Eukaryotic cells have internal membranes that compartmentalize their functions
5. Which two domains consist of prokaryotic cells?
Archaea, Bacteria
half-dozen. A major difference betwixt prokaryotic and eukaryotic cells is the location of their Dna.
Describe this difference.
