Question 2 Not yet graded / 4 pts
Briefly explain how a Transmission Electron Microscope (TEM) forms an
image of subcellular organelles, substrates, and viral particles.
Your Answer:
Transmission Electron Microscope forms an image by transmission of
light through the smaple and making the image visible such that the
subcellular images are visible; able to be seen unlike in the Scanning
Electron Microscope.
Answer: An image is formed from the interactions of electrons
as they pass through a thin sectioning of the sample that is
coated heavily in a preservative. An image from a TEM is
visualized in 2-D rendering.

Question 4 Not yet graded / 4 pts
Describe the primary distinction between prokaryotic and eukaryotic cells.
Your Answer:
Prokaryotic Cell do not contain a nucleus in which all organelles are
present inside of them that carry genetic substances like DNA unlike the
Eukaryotic cells that contain a nucleus
Answer: Eukaryotic cells have a defined, membrane-bound
nucleus that contains the genetic material. Prokaryotic cells
do not contain a nucleus, and their genetic material is found
free-floating in the cytoplasm.
