Question 1 pts
Match each of the following organelles with the correct description.
Nucleus Contains genomic content i
Endoplasmic reticulum Series of membrane-enclos
Correct!
Lysosomes Contain hydrolytic enzymes
Chloroplasts Site of photosynthesis
Correct!

Correct!
Question 2 Not yet graded /
4 pts
, Briefly explain how a Scanning Transmission Electron
Holography Microscope (STEHM) works and what it is
specifically used to see.
Your Answer:
It emmits electrons instead of beams of light. The electrons
will pass through the sample and allow for viewing. SEM and
TEM are used differently, one looks at the outside shell of
sample or cell and the other looks at the inside of the cell.
One is a 3-D image and the other is 2D.
Answer: An image is formed using an electron beam
but coupled with a holography technique to study
surfaces of proteins and subcellular structures. A
STEHM has the capacity to magnify subatomic
structures up to 20 million times larger than what can
be viewed with the naked eye.
