Your science class is observing the organisms found in local pond water. You have discovered this paramecium and are hoping to observe how the paramecium injects food. Your lab partner suggests using an electron microscope to see all the details in 3-D. You disagree: you believe a light microscope must be used. Using the table, support your decision to use a light microscope.
A) The paramecium is not very small It can easily be observed using the light
microscope
B) You want to observe life processes. You cannot use an electron microscope
to observe living specimens.
C) In order to see the paramecium, you must stain the slide. You cannot stain
a slide if using an electron microscope.
D) The beam of electrons used in the electron microscope is too dangerous to be used in a high school classroom environment.
