30
Q

Which of the following factors would increase the rate of diffusion?

A
  • Decreased molecular size
  • Larger Concentration gradient
  • Thinner Media
31
Q

A defining characteristic that distinguishes prokaryotic and eukaryotic organisms is the lack of a cell membrane in prokaryotes.

A

FALSE

32
Q

Which of the following are found in both plant and animal cells?

A
  • Mitochondria
  • Golgi Complexes
  • Endoplasmic Reticulum
33
Q

Which of the following is located outside of the cell membrane and provides structural support to plant and prokaryotic cells?

A

-Cell wall

34
Q

The endoplasmic reticulum

A

-Is where digestive enzymes are stored

35
Q

Did diffusion across the membrane occur for the iodine solution?

A

-YES

36
Q

Did diffusion across the membrane occur for the starch solution?

A

No

37
Q

Did diffusion across the membrane occur for the glucose solution?

A

Yes

38
Q

What happened to the cell to cause it to shrink?

A

-Due to the hypertonic solution, water is leaving the cell.

39
Q

What is happening to the cell since there seems to be no change?

A

-Since the solution is isotonic, there is no net movement of water.

40
Q

What happened to the cell to cause it to swell?

A

-Due to the hypotonic solution, water is entering the cell.
