What will most likely be the result if all the mitochondria are removed from a plant cell?

•  It won’t make energy as effectively
• It will lose water through osmosis
• It will break down the ribosomes in the cell
• It will be unable to photosynthesize

Which statement best describes the plasma membrane of a living plant cell?  

•  It selectively regulates the passage of substances into and out of the cell
•  It is composed of proteins and carbohydrates only
•  It has the same permeability to all substances found inside or outside the cell
• It is a double protein layer with floating lipid molecules

What is the difference in the way nucleotides are arranged in a prokaryotic and eukaryotic cell?

• Prokaryotes don’t have nucleotides
• Prokaryotes have linear DNA, eukaryotes have circular DNA
•  Eukaryotes have linear DNA, prokaryotes have circular DNA
• They both arrange nucleotides the same way

How are prokaryotic and eukaryotic cells similar?

• Both contain a nucleus
•  Both contain ribosomes
• Both contain membrane-bound organelles
• Both contain cell walls

You are working in a lab and your partner tells you he found a new type of single celled plant.  What will you look for to check to make sure he is correct?

• Mitochondria 
• Nucleus 
• Chloroplasts 
• Plasmids

What characteristic of mitochondria and chloroplasts allow them to do reactions more effectively?

• They are really big
• They have their own DNA
• They have highly folded inner membranes
• They can make enzymes on their own

In a plant cell, what two places would you expect to find a high concentration of carbohydrates?

• Cell Wall & Vacuoles
• Nucleus & Ribosomes
• Plasma Membrane & Mitochondria
• Cytoplasm & Plasmids

Which of the following structures is NOT found in every living cell? 

• Plasma Membrane
• Nucleus 
• Ribosomes 
• Cytoplasm
