Class 16 Opener 10/22/15What is the difference between active
and passive transport when discussing cellular membranes? Active
transport requires energy (ATP) and passive transport does
not.Image A is an example of ? Image A is an example of active
transport.How is diffusion different than osmosis? Osmosis is a
specialized form of diffusion. Diffusion may or may not be a form
of osmosis. Specifically osmosis is the diffusion of water across a
semipermeable membrane.

Opener Oct. 26Lab: soap bubble What did the bubble represent? It
represented a cell membrane.Explain how the skin of the bubble
differs from a cell membrane. The soap bubble non-polar tails face
in the opposite direction of a cell membrane tails. Cell membrane
non-polar tails face each other while the polar heads face outward
from each other.

layers of phospholipids make up a cell membrane.Describe the
differences between active and passive transport. Active transport
uses ATP (energy) to move substances through membrane and passive
does not.

Lipid soluble molecules are transported through the cell
membranes more easily than water soluble moleculesSmall molecules
are transported through the membrane more easily than large
moleculesThe higher the charge on the molecule, the harder it is
for it to be transported through the membrane

Data Table ChecklistIs there sufficient data to know whether
hypothesis is correct? Are the data recorded in the form of a
table? Is there a title? Is the title clear and does it reflect the
purpose of the data table? Is the table organized, rows and columns
are labeled, and units are indicted Is the independent variable in
the first column? Is the independent variable named? Is the
independent variable unit included, if appropriate? Is there a
column (sometimes with sub-columns) for the dependent variable? Is
the dependent variable named? Is the dependent variable unit
included, if appropriate? Are there trial sub-columns under the
dependent variable (one for each trial)? Is there a column for a
derived or calculated quantity? Is a sample calculation is given,
if calculations are required? Is the derived (e.g., average) column
on the far right? Is the derived quantity named, if appropriate? Is
the derived quantity unit included, if appropriate? Are the derived
calculations correct? Does the data matches what was stated to be
collected in the procedures? Are data recorded correctly? Is the
source of the data noted? If there is more than one table the
tables are numbered consecutively. Are SI Units used?

Graph ChecklistIs data transformed into the form of a graph? Is
the graph type appropriate for the data being displayed? Does the
graph have a descriptive title? Does the graph have a label on both
axes indicating variables and units? Is the independent variable on
the x-axis? Is the dependent variable on the y-axis? Does the graph
have the proper scale (the appropriate high and low values on the
axes)? Is the scale of graph is regular and consistent? Is data
plotted correctly and clearly? Is the graph well-spaced on the
page? Is the graph neat, clean and easy to read? Is there
appropriate and descriptive key? Are SI Units used?
