Review: Diffusion State Lab

This laboratory setup would most likely be used to demonstrate the process of

• active transport

• replication

• cellular respiration

• diffusion

Which molecules went through diffusion in this lab?

• Glucose and Starch

• Glucose and Starch Indicator (Iodine)

• Glucose and Glucose Indicator

• Starch and Starch Indicator (Iodine)

What will the solutions in the beaker and the tubing look like after 20 minutes? 

• The indicator solution in the beaker will be blue black and the starch solution in the tubing will not change color.

• The starch solution in the tubing will be blue black and the indicator solution in the beaker will not change color.

• Neither the indicator solution nor the starch solution will be blue black.

• Both the indicator solution and the starch solution will be blue black.

Identify the color of the contents of the artificial cell after two hours. 

• amber

• blue-black

• orange

• milky white

After two hours, the color of the liquid in the beaker did not change. This shows that

• starch did not pass out of the artificial cell

• glucose moved from the artificial cell into the beaker

• starch was digested to glucose in the artificial cell

• glucose molecules combined to produce starch in the artificial cell

Which statement best describes what will most likely happen after several minutes?

• The model cell will shrink.

• The contents of the model cell will change color.

• The liquid outside the model cell will change color.

• The model cell will rupture.

How do we know glucose diffused out of the cell?

• The solution in the beaker turned orange

• We took a sample of the outside solution, added glucose indicator/heat and it turned orange

• The solution in the beaker turned black.

• The solution in the beaker stayed amber.

The diagram represents a cell and its changes as a result of laboratory procedure "A". Describe procedure "A" and why it would cause the change shown.

• (1) Water was added

  (2) Water then entered the cell resulting the cytoplasm and cell membrane to push up against the the cell wall

• (1) Water was added

  (2) Water then left the cell resulting in the cytoplasm and cell membrane to shrink away from the cell wall.

• (1) Salt was added

  (2) Water then left the cell resulting in the cytoplasm and cell membrane to shrink away from the cell wall.
