Honors Biology Unit 3 Exam Questions
and Answers
What are the three parts of the cell theory? ✅Every cell is made up of one or more
cells. Cells are the basic unit of structure. All cells are from pre-existing cells.
How was the cell theory discovered? ✅The cells theory was discovered by Robert
Hooke when he was looking at a peice of cork under a microscope where the chambers
he saw reminded him of the cell/rooms where monks slept in their monasteries
What is the difference between a theory and a hypothesis? How is a theory developed?
✅A hypothesis is constructed before any research has been done. A theory, on the
other hand, is supported by evidence and is created through the process of the scientific
method
What does resolution mean in the context of microscopes? ✅The smallest distance by
which two objects can be separated and still be distinguished.
What does magnification mean in the context of microscopes? ✅An increase in the
apparent size of an image so as to resolve smaller separations between objects
What are the basic parts of a compound light microscope? ✅ocular lens/eyepiece,
objective lens, stage, stage clips, arm, fine resolution knob, coarse resolution knob
What are the differences between a light microscope and an electron microscope?
✅Magnification: Electron microscopes have much higher magnification than light
microscopes. Light microscope is used for identify different kinds of bacteria. Electron
microscopes are used for view thin specimens through which electrons can pass
generating a projection
What are the differences between a light microscope and a dissection scope? ✅1. The
compound microscope uses only transmitted light, whereas the dissecting microscope
uses transmitted and reflected light so there won't be shadows on the 3D subjects.
2. Each eye has its own objective in the dissecting microscope so that 3D objects can
be seen as 3D, whereas the compound microscope has two oculars, but only one
objective for both eyes.
3. Compound Microscopes have greater magnifications, but lower resolutions than the
Dissecting microscopes.
What are the differences between a scanning electron microscope and a transmission
electron microscope? ✅Rather than the broad static beam used in TEM, the SEM
