Biology VBA Review 3 - Unit 2: Cell Structure & Function

The model to the right shows a student’s model of the Cell Theory. What part of the Cell Theory does it represent?

• All cells come from other preexisting cells

• All living things are made of cells

• Cells form through spontaneous generation

• Cells are the basic structural and functional units of life

In science, a theory is an explanation for some phenomenon that is based on observation, experimentation, and reasoning. One important theory in biology is the cell theory. What kind of observations led to the development of the cell theory?

• Testing of first vaccines

• Isolations of DNA and RNA

• Microscopic views of plants and animals from the compound microscope

• Discoveries of fossil bacteria by using the scanning electron microscope

A Florida Panther and a microscopic pond organism, paramecium, are both living things. According to the Cell Theory, what can you conclude about these two very different organisms?

• A. They are made of many cells.

• B. They are made of one or more cells.

• C. They come from the same kind of cell.

• D. They come from noncellular structures

At one point, people thought disease was caused by bad behavior. With the invention of the microscope came the discovery of bacteria. The Germ Theory was developed which states that disease results from microorganisms. Why did this change in belief occur? 

• It quickly became obvious that germs cause disease.

• The person who invented the microscope became ill.

• The proponents of the germ theory had political power.

• New evidence prompted revision to the original ideas.

Which type of microscope would you use to see a one-celled organism with very little detail at 100x magnification?

• Transmission Electron Microscope

• Dissecting Microscope

• Scanning Electron Microscope

• Compound Light Microscope

Which microscope would you use to view tiny organisms that live in pond water or streams?

• Dissecting Microscope

• Compound Light Microscope

• Transmission Electron Microscope

• Scanning Electron Microscope

A student is looking at a cell under a microscope and notices that the cell does not have a nucleus but does have a cell wall. What type of cell is she likely observing?

• Prokaryote

• Animal Cell

• Plant Cell

• Eukaryote

If a student wanted to observe the folds in a Golgi Body or Rough Endoplasmic Reticulum in detail, which microscope would he use?

• Dissecting Microscope

• Compound Light Microscope

• Transmission Electron Microscope

• Scanning Electron Microscope

Which structures in this cell image are only found in plant cells?

• A. A, C, F

• B. G, A, C

• C. H, A, F

• D. I, F, H

Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown. Which of the cells viewed is most likely a plant cell?

• Cell Y

• Cell Z

• Cell W

• Cell X
