Name three organelles or cell structures involved in the synthesis of proteins. Explain the specific functions of all three.
Answers may vary.
100
What is the single most reliable characteristic that distinguishes between prokaryotic and eukaryotic cells?
What is the presence of a defined nucleus in eukaryotes.
100
The potato lab illustrated osmosis. Define osmosis.
Osmosis is the diffusion of water across a selectively permeable membrane.
100
Do plant cells have mitochondria? If they make their own food, then why would they need mitochondria?
Yes, plant cells have mitochondria. They make their own food (glucose sugar) in the mitochondria, but this food must be burned (metabolized) in the mitochondria to supply the plant with energy.
100
Explain the behavior of a human red blood cell in hypertonic and hypotonic solutions.
Hypertonic - Cell will crenate or shrivel Hypotonic - Cell will swell and perhaps burst
200
What is one function of SMOOTH endoplasmic reticulum?
What is synthesis of lipids or detoxification of certain chemicals
200
Do prokaryotes, eukaryotes, or both have ribosomes within the cytoplasm?
What is both.
200
What two changes occurred in the egg left in the beaker of vinegar and why did they occur?
The shell dissolved (acetic acid in the vinegar dissolved the calcium shell of the egg), and the cell membrane swelled in size (the vinegar was hypotonic to the contents of the egg)
200
In the movie "Back to the Future," how much energy did it take to make the silver DeLorean travel through time?
What is 1.21 gigawatts
200
Does active transport require energy? Is it upward or downward along a concentration gradient?
What is yes; upward.
300
This structure, made of cellulose, gives plant cells structure and support.
What is cell wall
300
What word describes the circular DNA structure of prokaryotes?
What is plasmid DNA
300
What kind of microscopes have we used in lab? What would you need to use to see the details of organelles?
What is compound light microscope; scanning electron microscope
300
Protein synthesis occurs on this organelle.
What is the ribosome.
300
Explain facilitated diffusion. Name one thing that crosses the membrane via facilitated diffusion.
Facilitated diffusion is the movement of specific molecules across the cell membrane through protein channels. Answers may vary (salts, ions, sugars)
400
These cell structures, only found in animal cells, function to anchor the spindle fibers at the poles during the movement of chromosomes during mitosis.
What are centrioles
400
Explain the basic idea of the Serial Endosymbiotic Theory.
What is the idea that early prokaryotes combined to form increasingly complex eukaryotic cells.
400
In the red onion lab, why did we use filter paper?
What is to wick the solutions (salt and tap water) across the sample of onion skin.

This San Francisco 49ers QB was game MVP in three of his four Super Bowl victories during the 1980s and 1990s.
Who is Joe Montana

Explain the difference between endocytosis and exocytosis. What is exocytosis used to remove?
Exocytosis is the removal of substances from the cell, while endocytosis is the intake of substances by the cell.
500
What process happens in the mitochondria, and what is the end product of this reaction?
What is cellular respiration, end products include ATP, CO2, and H2O
500
Name the four kingdoms of living things that are classified as eukaryotes.
What are plants, animals, fungi, and protists

The "cell model" lab illustrated selective permeability. What substance(s) passed through the dialysis tubing and what did not?
Iodine and water passed through, while corn starch did not.

This Hall of Fame fastball pitcher, multiple Cy Young Award winner, and one of Mr. Askins' childhood heroes holds the all-time MLB strikeout record (MLB 1965-1993).
Who is Nolan Ryan.
500
Explain the difference between pinocytosis and phagocytosis.
Both are forms of endocytosis. Pinocytosis is the intake of liquid molecules (cell drinking), while phagocytosis is the intake of solids (cell eating).
