Final Jeopardy

$100 Question from Lab Testing

The solution used to test the presence of starch

$100 Answer from Lab Testing

What is iodine?

$200 Question from Lab Testing

After using Benedict’s solution, a green colour is present in the test tube. What does this represent?

$200 Answer from Lab Testing

What is low glucose levels?

$300 Question from Lab Testing

What was smaller the glucose or the dialysis membrane pores? Explain.

$300 Answer from Lab Testing

Glucose, because the glucose diffused out of the dialysis pores?

$400 Question from Lab Testing

When a bacterial cell was placed in a hypertonic solution, what would happen?

$400 Answer from Lab Testing

Plasmolysis would occur, in which the cell wall pulls away from the cell membrane?

$500 Question from Lab TestingExplain the following diagram:

$500 Answer from Lab Testing

In a hypertonic environment, molecules start to diffusion down their concentration gradient until they reach a isotonic state.

$100 Question from Tonicity

A solution that has more solutes comparedto the cell.

$100 Answer from Tonicity

What is hypertonic?

$200 Question from Tonicity

A solution that has less solute then the cell.

$200 Answer from Tonicity

What is hypotonic?

$300 Question from Tonicity

A plant cell will demonstrate plasmolysis when placed in this type of solution.

$300 Answer from Tonicity

What is a hypertonic solution?

$400 Question from Tonicity

A plant was placed in this type of solutionif it became turgid (which is normal).

$400 Answer from Tonicity

What is hypotonic?

$500 Question from Tonicity

This will happen when a blood cell is placed in a hypertonic environment.

$500 Answer from Tonicity

What is crenation?

$100 Question from Passive Transport

The direction of flow in diffusion.

$100 Answer from Passive Transport

What is from high conc. to low conc. (down its concentration gradient)?

$200 Question from Passive Transport

If we place a gummy bear in water, and let it sit overnight, this process would occur.

$200 Answer from Passive Transport

What is osmosis?

$300 Question from Passive Transport

This type of passive transport requiresproteins.

$300 Answer from Passive Transport

What is facilitated diffusion?

$400 Question from Passive Transport

A small solid molecule wants to get into the intracellular space (from the extracellularregion) and will travel down its conc. gradient.It will use this type of transport.

$400 Answer from Passive Transport

What is diffusion?

$500 Question from Passive Transport

This factor can increase the rate of diffusion.

$500 Answer from Passive Transport

What is an increase in temperature?What is an increase in concentration of solutes?

$100 Question from Active Transport

These two factors are required for active transport to take place.

$100 Answer from Active Transport

What are proteins and energy?

$200 Question from Active Transport

When a small solid enters the cell.

$200 Answer from Active Transport

What is phagocytosis?

$300 Question from Active Transport

This type of transport is when a molecule sneaks in with another molecule at the same time.(almost like a piggy back)

$300 Answer from Active Transport

What is cotransport?

$400 Question from Active Transport

A cell that uses active transport will generally have more of these organelles.

$400 Answer from Active Transport

What are mitochondria?

$500 Question from Active Transport

When a particle enters the cell, it first forms this in order to be further broken down.(Hint: think of the video animation)

$500 Answer from Active Transport

What is a phagolysosome?

$100 Question from Potpourri

A particle will leave the intracellularfluid and enter the extracellular fluidby this process.

$100 Answer from Potpourri

What is exocytosis?

$200 Question from Potpourri

When the water is balanced within a cellAnd its environment, it is said to be in this type of state.

$200 Answer from Potpourri

What is isotonic?

$300 Question Potpourri

The following diagram represents what process?

$300 Answer from Potpourri

What is a receptor mediated diffusion?

$400 Question from Potpourri

During the lab, the iodine entered the dialysis tubing through this process?

$400 Answer from Potpourri

What is diffusion?

$500 Question from Potpourri

If a cell was placed in a highly concentrated starch solution, what direction would the starch travel?

$500 Answer from Potpourri

The starch would not enter the cell, because it is too large of a moleculeto fit in the membrane pores

Final JeopardyUse Biology vocabulary and explain the following graph:

Final Jeopardy Answer

The potato was placed in a hypertonic solution. As the concentration of sugar increases (from 0 to 8M) more water will leave the potatovia osmosis, and therefore decreases the cell massof the potato. This will result in a non-turgid/limppotato and plasmolysis may occur.
